(God of Israel and Father of Jesus Christ)
The Church of God that is in Christ Jesus keeps The Seventh Day Sabbath and Holy Feast Days of God, The Father of Jesus Christ- as part of the righteous manner of life that God Himself instructs man to follow:
Exodus 31:13-16 (KJV)
Speak thou also unto the children of Israel, saying, Verily My Sabbaths ye shall keep: for it is a sign between me and you throughout your generations; THAT YE MAY KNOW that I am The LORD that doth sanctify you.
 Ye shall keep The Sabbath therefore; for IT IS HOLY UNTO YOU: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people.  Six days may work be done; BUT IN THE SEVENTH is the Sabbath of rest, HOLY TO THE LORD: whosoever doeth any work in the sabbath day, he shall surely be put to death.
 Wherefore the children of Israel shall keep the sabbath…
Most of Christianity claims that The Seventh Day Sabbath was only given to the Israel of The Old Testament, or merely to The Jews, to keep… That Jesus somehow changed, abolished, or annulled The Seventh Day Sabbath Commandment. This would literally mean that Jesus Christ was abolishing (or annulling) The Fourth Commandment found in The Ten Commandments of His own Heavenly Father:
John 8:54-55 (NASB)
Jesus answered, “If I glorify Myself, My glory is nothing; it is My Father who glorifies Me, of whom you say, ‘He is our God’;
 and you have not come to know Him, but I know Him; and if I say that I do not know Him, I shall be a liar like you, but I do know Him, AND KEEP HIS WORD.
Exodus 20:10 (KJV)
But The Seventh Day is The Sabbath of The LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
 For in six days the Lord made heaven and earth, the sea, and all that in them is, and RESTED The Seventh Day: WHEREFORE The LORD BLESSED The Sabbath Day, AND HALLOWED It.
Luke 4:14-16 (NASB)
And Jesus returned to Galilee in the power of the Spirit; and news about Him spread through all the surrounding district.  And He began teaching in their synagogues and was praised by all.
 And He came to Nazareth, where He had been brought up; and as was His custom, He entered the synagogue on the Sabbath, and stood up to read.
God (Jesus’ Father) “blessed” (put a blessing on) The Seventh Day of the week.
AND, it says that God (Jesus’ Father) “Hallowed” it- or, declared The Seventh Day of the week to be a “holy day“.
The Lord of Christianity, Jesus is clear about anyone who would go against His Father’s Ten Commandments:
Matthew 5:17-20 (KJV)
THINK NOT that I am come to destroy the law, or the prophets: I AM NOT COME TO DESTROY, but to fulfil.  For verily I say unto you, TILL HEAVEN AND EARTH PASS, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.  For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
The Word of God is what saint Paul says is The Definer of doctrine for The Church of Jesus-
2 Tim. 3:15-17 (KJV)
And that from a child thou hast known the HOLY SCRIPTURES, WHICH ARE ABLE to make thee wise unto salvation THROUGH FAITH which is in Christ Jesus.
 ALL SCRIPTURE is given by inspiration of God, and IS PROFITABLE…
– (helpful or serviceable, i.e. advantageous)
and IS PROFITABLE FOR DOCTRINE, for reproof, for correction, FOR INSTRUCTION IN RIGHTEOUSNESS:  THAT THE MAN OF GOD MAY BE PERFECT, thoroughly furnished unto all good works.
“The Word of God“/”The Sacred Writings“/”The Scriptures” are clear that “The Seventh Day is The Sabbath of The Lord your God” and It is NOT to be “abolished“, nor “annulled” in any way.
God (as recorded by The Holy Scriptures) has proclaimed and commanded “The Seventh Day” as “The Sabbath of The LORD“, and Jesus Himself has said that no man should try to annul it.
God even warned us that there was going to come a time when men would indeed think to change times and seasons, and would cast The Truth to the ground…
Daniel 7:25 (NASB)
…’And he will speak out against the Most High and wear down the saints of the Highest One, and he will intend to make alterations in times and in law…
Daniel 8:12 (NASB)
…And on account of transgression the host will be given over to the horn along with the regular sacrifice; and it will fling TRUTH to the ground and perform its will AND PROSPER.
– Belief AND The Obedience to “The Truth” is the means of becoming Holy; it is what “sanctifies” each individual that God is calling to Him through the repentance and baptism that is in Jesus Christ, His Son:
John 17:17-19 (KJV)
Sanctify them through thy truth: THY WORD IS TRUTH.  As thou hast sent me into the world, even so have I also sent them into the world.  And for their sakes I sanctify myself, that THEY also might BE SANCTIFIED THROUGH THE TRUTH.
2 Thes. 2:2-15 (NASB)
 ……to the effect that the day of the Lord has come.
 Let no one in any way deceive you, for it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction,  who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God.  Do you not remember that while I was still with you, I was telling you these things?  And you know what restrains him now, so that in his time he may be revealed.  For the mystery of lawlessness is already at work; only he who now restrains will do so until he is taken out of the way.  And then that lawless one will be revealed whom the Lord will slay with the breath of His mouth and bring to an end by the appearance of His coming;  that is, the one whose coming is in accord with the activity of Satan, with all power and signs and false wonders,  and with all the deception of wickedness FOR THOSE WHO PERISH, because they did not receive THE LOVE OF THE TRUTH SO AS TO BE SAVED.
 And FOR THIS REASON God will send upon them a deluding influence so that they might believe WHAT IS FALSE,
* KJV “that they should believe A LIE”
 in order that they all may be judged who DID NOT BELIEVE THE TRUTH, but took pleasure in wickedness.
 But we should always give thanks to God for YOU, BRETHREN beloved by the Lord, because God has chosen you from the beginning FOR SALVATION THROUGH sanctification by the Spirit AND FAITH IN THE TRUTH.  And IT WAS FOR THIS HE CALLED YOU through our gospel, that you may gain the glory of our Lord Jesus Christ.
 So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter from us.
The Truth speaks to all of us to this very Day… It declares to us that The Seventh Day Sabbath of God is a special and sanctified day in the eyes of God. It is for this reason that God says that anyone who considers themselves HIS people should respect His Day:
… Wherefore the children of Israel shall keep the sabbath,
* “Israel” means ” he will rule with God”
Galatians 3:7, 9 (NASB)
Therefore, BE SURE THAT it is those who are of faith who are sons of Abraham……
…… So then those who are of faith are blessed with Abraham, the believer.
Galatians 6:15-16 (KJV)
For IN Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but A NEW CREATURE.
 And AS MANY AS WALK ACCORDING TO THIS RULE, peace be on them, and mercy, and upon THE ISRAEL OF GOD.
Romans 9:6-8 (NASB)
But it is not as though the word of God has failed. For they are not all Israel who are descended from Israel;  neither are they all children because they are Abraham’s descendants, BUT: “through Isaac your descendants will be named.”  THAT IS, it is not the children of the flesh who are children of God, but THE CHILDREN OF THE PROMISE are regarded as descendants.
… Wherefore THE CHILDREN OF ISRAEL shall keep The Sabbath, to observe the sabbath throughout their generations, for A PERPETUAL COVENANT.
 IT IS A SIGN between me and the children of Israel FOR EVER: for in six days the Lord made heaven and earth, and on the seventh day he rested, and was refreshed.
Hebrews 4:9-14 (NASB)
THERE REMAINS therefore A Sabbath rest for the people of God.
* See KJV note: “Literally, ‘a keeping of The Sabbath‘ “
… For the one who has entered His rest has himself also rested from his works, as God did from His.
– God’s Word Reveals that The Churches of the Apostles’ Time Kept THE SEVENTH DAY “Sabbath”, AND The Holy Feast Days of The Father of Jesus Christ.
The Truth testifies that Paul himself kept The Seventh Day Sabbath and The Holy Feast Days, just as all The Church of his time did:
Acts 17:1-3 (KJV)
Now when they had passed through Amphipolis and Apollonia, they came to Thessalonica, where was a synagogue of the Jews:  And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the scriptures,  Opening and alleging, that Christ must needs have suffered, and risen again from the dead; and that this Jesus, whom I preach unto you, is Christ.
Acts 16:13 (NASB)
And ON THE SABBATH DAY we went outside the gate to a riverside, where we were supposing that there would be a place of prayer; and we sat down and began speaking to the women who had assembled.
Acts 13:14 (KJV)
But when they departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the sabbath day, and sat down.
Acts 18:2-5 (NASB)
And he found a certain Jew named Aquila, a native of Pontus, having recently come from Italy with his wife Priscilla, because Claudius had commanded all the Jews to leave Rome. He came to them,  and because he was of the same trade, he stayed with them AND THEY WERE WORKING; for by trade they were tent-makers.  And he was reasoning in the synagogue EVERY SABBATH and trying to persuade Jews and Greeks.
 BUT when Silas and Timothy came down from Macedonia, PAUL BEGAN DEVOTING HIMSELF COMPLETELY TO THE WORD……
Notice the one day out of the work-week here that Paul was able to devote himself completely to The Word and the preaching? It was on The Holy (“sanctified”) SEVENTH DAY Sabbath of God, his Father through Jesus Christ. Then notice what he is able to do when it was that Silas and Timothy arrived with their support for the work. It says that Paul was able to “COMPLETELY devote his time to The Word”- at all times that is, not just on the weekly Sabbaths. This record shows Paul kept The Seventh Day as a Holy Day Sabbath- he did so through THE OBEDIENCE to The Ten Commandments of God, as taught by Jesus Christ.
As for The Feasts of The LORD being kept by saint Paul (The Apostle to the gentiles)-
Acts 18:21 (KJV)
…But bade them farewell, saying, I must by all means KEEP THIS FEAST that cometh in Jerusalem: but I will return again unto you, if God will. And he sailed from Ephesus…
Acts 20:16 (NASB)
For Paul had decided to sail past Ephesus in order that he might not have to spend time in Asia; for he was hurrying to be in Jerusalem, if possible, on the day of Pentecost.
1 Cor. 16:8 (KJV)
But I will tarry at Ephesus until Pentecost.
Notice Paul marking time by The Holy Feast Days of The God of Israel, The Father of Jesus Christ?
And, for anyone who would speculate– (i.e. go aside from God’s Word) and present the idea that perhaps since Paul was a Jew, he was merely abiding by “the customs” of The Jews…well, for that person God has preserved Paul’s own words to A GENTILE believing Church that was “under Grace“:
1 Cor. 5:7-8 (NASB)
…For Christ OUR PASSOVER also has been sacrificed.  LET US THEREFORE CELEBRATE THE FEAST, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth..
The Feast that The Gentile Church of Corinth was being instructed to celebrate here, was The Feast of Passover and The Days of Unleavened Bread (The Law of God for His Holy Sabbaths, found in Lev. 23)
Hebrews 4:9-14 (NASB)
THERE REMAINS therefore A Sabbath rest for the people of God.
* See KJV note: “Literally, ‘a keeping of The Sabbath’ “
 For the one who has entered His rest has himself also rested from his works, as God did from His.
 LET US therefore be diligent to enter that Rest, lest anyone fall through following the same example of disobedience.  For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart.  And there is no creature hidden from His sight, but all things are open and laid bare to the eyes of Him with whom we have to do.
 Since then we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession.
Besides all these scriptures, we are also granted a glimpse By God into how He will be doing things in The Kingdom of His Son, Jesus Christ- after it is that He sends Him to this earth to “rule with a rod of iron“…
Psalm 2:7-10 (KJV)
I will declare the decree: The LORD hath said unto me, Thou art my Son; this day have I begotten thee.  Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.  Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter’s vessel.  Be wise now therefore, O ye kings: be instructed, ye judges of the earth.  Serve The LORD with fear, and rejoice with trembling.  Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
God Himself shows us in His Sacred Scriptures that HE will cause HIS will to be accomplished over ALL FLESH, in the end of the ages of man’s rulership on earth…
In the Prophets, God clearly says that ALL FLESH will be made to respect His “SEVENTH Day Sabbath“- that is, they will be taught obedience to the 4th Commandment, “Remember The Sabbath Day, to keep it holy“- AND to keep HIS holy Feast Days as well. Again, all of these days are described and listed for us in Leviticus 23, as days that have been Sanctified (- i.e. made holy) by The Father of Jesus Christ…
God’s “Seventh Day Sabbath” and Ten Commandments WILL be kept holy in the age of ‘The Millenium‘; that is the age to come that will be directly under Christ Jesus’ rulership…
God has Promised that “ALL FLESH” will keep HIS Sabbath(s) and Holy Feast Days:
Isaiah 66:22-24 (KJV)
For as the new heavens and the new earth, which I will make, shall remain before me, saith the Lord, so shall your seed and your name remain.
 And IT SHALL COME TO PASS, that from one new moon to another, AND FROM ONE SABBATH TO ANOTHER, SHALL ALL FLESH come to worship before me, saith The LORD.
The Way that is taught by Christ Jesus Himself, and His sanctified Apostles, instructed all everywhere in the way of “repentance” from sin (- “sin is the transgression of The Law” – 1 John 3:4) for the kingdom of Heaven is at hand…
This would be why Jesus’ doctrine (teachings) reveal that “The SEVENTH Day Sabbath” is His Holy Day, as an obedient Son to His Father’s Word… Obedience to The 4th Commandment of The Father is then a natural part of the obedience that is IN Christ Jesus our Lord…
Turning from Disobedience to Obedience is clearly the message that is given by Him to all of us- and the message that will be taught on the day He establishes HIS Kingdom on this earth:
2 Peter 3:9-18 (NASB)
The Lord is not slow about His promise, as some count slowness, but is patient toward you, not wishing for any to perish but for ALL TO COME TO REPENTANCE.
Matthew 4:17 (KJV)
From that time Jesus began to preach, and to say, REPENT: for the kingdom of heaven is at hand.
Acts 17:30-31 (NASB)
“Therefore having overlooked the times of ignorance, God IS NOW declaring to men that ALL EVERYWHERE should REPENT,  because He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead.”
… But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the earth and its works will be burned up.
 Since all these things are to be destroyed in this way, WHAT SORT OF PEOPLE OUGHT YOU TO BE in holy conduct and godliness,  looking for AND hastening the coming of the day of God, on account of which the heavens will be destroyed by burning, and the elements will melt with intense heat!  But according to His promise we are looking for new heavens and a new earth, IN WHICH RIGHTEOUSNESS DWELLS.
 Therefore, beloved, since you look for these things, be diligent to be found by Him in peace, spotless and blameless,  and regard the patience of our Lord to be salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you,  as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction.  You therefore, beloved, knowing this beforehand, be on your guard lest, being carried away by the error of unprincipled men, you fall from your own steadfastness,  but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory, both now and to the day of eternity. Amen.
Zech. 14:16-19 (KJV)
And IT SHALL COME TO PASS, that EVERY ONE that is left OF ALL THE NATIONS which came against Jerusalem shall even go up from year to year to worship the King, the Lord of hosts, AND TO KEEP THE FEAST OF TABERNACLES.  And it shall be, that WHOSO will not come up OF ALL THE FAMILIES OF THE EARTH unto Jerusalem to worship the King, the Lord of hosts, even upon them shall be no rain.  And if the family of Egypt go not up, and come not, that have no rain; there shall be the plague, wherewith the Lord will smite the heathen that come not up TO KEEP THE FEAST OF TABERNACLES.
 This shall be the punishment of Egypt, and the punishment of ALL NATIONS that come not up TO KEEP THE FEAST OF TABERNACLES.
God clearly shows that HIS holy Sabbaths will be observed during Christ rulership on Earth, after His 2nd coming.
This is revealed to us as well, in the laws and rules for The Temple during that age to come:
Ezekiel 46:1 (KJV)
Thus saith the Lord God; The gate of the inner court that looketh toward the east shall be shut THE SIX WORKING DAYS; BUT ON THE SABBATH it shall be opened, AND in the day of the new moon it shall be opened……
“The East Gate” is for ALL who go to worship before the God of Jesus Christ at the Temple. Notice the rules for The East Gate’s hours for being open and closed, AND what it reveals to us about The Law of God ruling during this age to come in Jesus Christ:
…… And the prince shall enter by the way of the porch of that gate without, and shall stand by the post of the gate, and the priests shall prepare his burnt offering and his peace offerings, and he shall worship at the threshold of the gate: then he shall go forth; but the gate shall not be shut UNTIL THE EVENING.
– As The Law of God has said all along:
Leviticus 23:32 (KJV)
…FROM EVEN UNTO EVEN, shall ye celebrate your Sabbath.
 LIKEWISE the people of the land shall worship at the door of this gate before the Lord in the sabbaths and in the new moons.
It is clear that God will rule the earth during The Age of Jesus Christ (commonly called, “The Millenium“)-
Rev. 20:1-6 (KJV)
And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.  And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,  And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
 And I saw thrones, and they sat upon them, AND JUDGMENT WAS GIVEN UNTO THEM…
Daniel 7:24-28 (KJV)
……And the ten horns out of this kingdom are ten kings that shall arise: and another shall rise after them; and he shall be diverse from the first, and he shall subdue three kings.  And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.  But the judgment shall sit, and they shall take away his dominion, to consume and to destroy it unto the end.  And the kingdom and dominion, and the greatness of the kingdom under the whole heaven, shall be given to the people of the saints of the most High, whose kingdom is an everlasting kingdom, and ALL DOMINIONS shall serve and obey him.  Hitherto is the end of the matter.
…AND I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and THEY lived and REIGNED WITH CHRIST A THOUSAND YEARS.
 But the rest of the dead lived not again until the thousand years were finished.
THIS is THE FIRST RESURRECTION.
 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ,
Notice: “…and shall reign with him a thousand years“.
It is clear that Jesus Christ will be sent to this earth by The Father to rule the earth for 1,000 years, as said here. The point is, the rulership of Christ Jesus (- “under Grace”) teaches and dictates that each person subject themselves to God, The Father, and keep HIS Commandments.
Again, God is very clear on this matter; that there will be 1,000 years of Jesus Christ ruling on the earth, beginning with His 2nd Coming:
Zech. 14:4-9 (KJV)
And HIS feet shall stand IN THAT DAY upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.  And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: AND The LORD MY GOD SHALL COME, AND ALL THE SAINTS WITH THEE……
1 Thes. 4:15-18 (NASB)
For this we say to you by the word of The Lord, that we who are alive, and remain UNTIL THE COMING OF THE LORD, shall not precede those who have fallen asleep.
 For The Lord Himself will descend from heaven with a shout, with the voice of the archangel, and with the trumpet of God; and THE DEAD IN CHRIST SHALL RISE FIRST……
Daniel 12:1-3 (NASB)
“Now at that time Michael, the great prince who stands guard over the sons of your people, will arise. And there will be a time of distress such as never occurred since there was a nation until that time; and at that time your people, everyone who is found written in the book, will be rescued.  “And many of those who sleep in the dust of the ground will awake, these to everlasting life, but the others to disgrace and everlasting contempt.
 “And those who have insight will shine brightly like the brightness of the expanse of heaven, and those who lead the many to righteousness, like the stars forever and ever.
Rev. 11:3-13 (NASB)
“And I will grant authority to my two witnesses, and they will prophesy for twelve hundred and sixty days, clothed in sackcloth.”……
… And when they have finished their testimony, the beast that comes up out of the abyss will make war with them, and overcome them and kill them.  And their dead bodies will lie in the street of the great city which mystically is called Sodom and Egypt, where also their Lord was crucified.
 And those from the peoples and tribes and tongues and nations will look at their dead bodies for three and a half days, and will not permit their dead bodies to be laid in a tomb.  And those who dwell on the earth will rejoice over them and make merry; and they will send gifts to one another, because these two prophets tormented those who dwell on the earth.  And after the three and a half days the breath of life from God came into them, and they stood on their feet; and great fear fell upon those who were beholding them.
 And they heard A LOUD VOICE FROM HEAVEN saying to them, “Come up here.” And THEY WENT UP INTO HEAVEN IN THE CLOUD, and their enemies beheld them.
 And in that hour there was a great earthquake, and a tenth of the city fell; and seven thousand people were killed in the earthquake, and the rest were terrified and gave glory to the God of heaven.
 For The Lord Himself will descend from heaven with a shout, with the voice of the archangel, and with the trumpet of God; and THE DEAD IN CHRIST SHALL RISE FIRST.
 THEN we who are alive and remain SHALL BE CAUGHT UP TOGETHER WITH THEM IN THE CLOUDS TO MEET THE LORD IN THE AIR, and thus we shall always be with the Lord.  Therefore comfort one another with these words.
…… And it shall come to pass IN THAT DAY, that the light shall not be clear, nor dark:  But it shall be one day which shall be known to the Lord, not day, nor night: but it shall come to pass, that at evening time it shall be light.  And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be.  And The LORD SHALL BE KING OVER ALL THE EARTH: in that day shall there be one LORD, and his name one.
Knowing, and looking ahead to these things, The Church of God that is in Jesus Christ our Savior will be demonstrating to this very day their “love of God” BY THE OBEDIENCE to HIS holy Commandments… Especially to “The Seventh Day Sabbath of The LORD your God”, since it is a sign between God and Israel “FOR EVER”.
The Church (The Body Members of Jesus Christ) to this day stand as a witness to all the earth that God’s holy Commandments are given for mankind’s good and their life; AND that IT IS EXPECTED of mankind to be found PRACTICING ALL OF THE TEN COMMANDMENTS under “The Way” that is obedient to Jesus Christ.
1 John 5:2-4 (KJV)
By this we know that we love the children of God, when we love God, AND keep his commandments.  For THIS is the love of God, THAT WE KEEP HIS COMMANDMENTS: and his commandments are not grievous.  For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
Acts 17:30-31 (NASB)
“Therefore having overlooked the times of ignorance, GOD IS NOW DECLARING to men that ALL EVERYWHERE SHOULD REPENT,  BECAUSE He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead.”
As has been said from Old times:
Psalm 2:1-12 (KJV)
Why do the heathen rage, and the people imagine a vain thing?
 The kings of the earth set themselves, and the rulers take counsel together, against the Lord, and against his anointed, saying,
 “Let us break their bands asunder, and cast away their cords from us.”
 He that sitteth in the heavens shall laugh: the Lord shall have them in derision.
 Then shall he speak unto them in his wrath, and vex them in his sore displeasure.
 Yet HAVE I SET MY KING UPON MY HOLY HILL OF ZION.
 I will declare the decree: The LORD hath said unto Me, Thou art my Son; this day have I begotten thee.  Ask of me, and I SHALL GIVE THEE THE HEATHEN for thine inheritance, AND THE UTTERMOST PARTS OF THE EARTH for thy possession.
 Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter’s vessel.
 Be wise now therefore, O ye kings: BE INSTRUCTED, ye judges of the earth.
 SERVE THE LORD WITH FEAR, and rejoice with trembling.
 KISS THE SON, lest he be angry, and ye perish from the way, when his wrath is kindled but a little.
BLESSED ARE ALL THEY THAT PUT THEIR TRUST IN HIM.
In the end, The Church of God, (- Each Body Member of Jesus Christ) will be found practicing “The Seventh Day Sabbath of The LORD” for the simple fact that Jesus Christ taught OBEDIENCE To The Father, and THIS is what all God’s true children will be practicing.
John 14:23-24 (NASB)
Jesus answered and said to him, “If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him, and make Our abode with him.  “He who does not love Me does not keep My words; and the word which you hear is not Mine, but the Father’s who sent Me.
Matthew 5:18-20 (KJV)
…For verily I say unto you, TILL HEAVEN AND EARTH PASS, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
 Whoever then annuls one of the least of THESE COMMANDMENTS, and so teaches others, shall be called least in the kingdom of heaven; BUT WHOEVER KEEPS AND TEACHES THEM, he shall be called great in the kingdom of heaven.  “For I say to you, that unless your righteousness surpasses that of the scribes and Pharisees, you shall not enter the kingdom of heaven.
Matthew 7:12 (NASB)
“Therefore, however you want people to treat you, so treat them, for THIS is The Law and The Prophets.
“The Golden Rule” (as man has labeled it)- is shown to be the obedience to The Law of God.
Matthew 22:37-40 (NASB)
And He said to him, ” ‘You shall love THE Lord your God with all your heart, and with all your soul, and with all your mind.’  “THIS IS THE GREAT AND FOREMOST COMMANDMENT.  “The second is like it, ‘You shall love your neighbor as yourself.’
 “ON THESE two COMMANDMENTS DEPEND THE WHOLE LAW and the Prophets.”
Notice that Jesus says there are TWO commandments to The Law of God- The Love of God being “The Foremost” or “Great Commandment”…Jesus points out that “the Great Commandment” is to Love God:
Matthew 22:35-38 (NASB)
And one of them, a lawyer, asked Him a question, testing Him,  “Teacher, which is the great commandment in the Law?”  And He said to him, ” ‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’  “This is the great and foremost commandment.
1 John 5:3 (NASB)
For this is the love of God, that we keep His commandments; and His commandments are not burdensome.
Luke 10:25-28 (NASB)
And behold, a certain lawyer stood up and put Him to the test, saying, “Teacher, what shall I do to inherit eternal life?”  And He said to him, “What is written in the Law? How does it read to you?”  And he answered and said, “You shall love THE Lord your God with all your heart, and with all your soul, and with all your strength, and with all your mind; and your neighbor as yourself.”
 And He said to him, “You have answered correctly; DO THIS, AND YOU WILL LIVE.”
Jesus reprimanded the Jews for NOT keeping The Law of God (practicing it in life)-
John 7:19 (KJV)
Did not Moses give you the law, and yet none of you keepeth the law? WHY GO YE ABOUT TO KILL me?
Jesus Himself kept (observed and practiced) The Seventh Day Sabbath of His Father. What it was that He refused to obey was the ideas of the Jews on what it meant to break The Sabbath (ideas that were not what God had commanded):
John 7:23-24 (NASB)
“If a man receives circumcision on the Sabbath that the Law of Moses may not be broken, are you angry with Me because I made an entire man well on the Sabbath?  “Do not judge according to appearance, but judge with Righteous Judgment.”
Deut. 1:17 (KJV)
Ye shall not respect persons in judgment; but ye shall hear the small as well as the great; ye shall not be afraid of the face of man; for the judgment IS GOD’S…
1 Cor. 4:6 (NASB)
Now these things, brethren, I have figuratively applied to myself and Apollos for your sakes, that in us you might learn NOT TO EXCEED WHAT IS WRITTEN, in order that no one of you might become arrogant in behalf of one against the other.
Notice- that we might learn not to exceed The Word of God (what is written) in our judgments… THIS is what The Jews had done, and judged people accordingly, and THIS is what Jesus Himself condemned them for.
For more on following God’s Judgments in life, refer to the study:
“Who Are We to Judge? God Commands us to Follow HIS Pre-Ordained Judgements in Our Lives”
This text-study deals with the commands from Jesus and Paul for our lifestyle as Christrians: “Judge Not According to Appearance, But Judge with Righteous Judgment“, AND, “…Learn not to exceed what is written, in order that no one of you might become arrogant…“)
Matthew 15:2-9 (NASB)
“Why do Your disciples transgress the tradition of the elders? For they do not wash their hands when they eat bread.”
 And He answered and said to them, “And why do you yourselves transgress the commandment of God FOR THE SAKE OF YOUR TRADITION?
 “For God said, ‘Honor your father and mother,’ and, ‘He who speaks evil OF FATHER OR MOTHER, LET HIM BE PUT TO DEATH.’  “BUT YOU SAY, ‘Whoever shall say to his father or mother, “Anything of mine you might have been helped by has been given to God,”  he is not to honor his father or his mother.’ And thus you invalidated the word of God for the sake of your tradition.
 “You hypocrites, rightly did Isaiah prophesy of you, saying,
 ‘This people honors Me with their lips,
But their heart is far away from Me.
 ‘But in vain do they worship Me,
Teaching as DOCTRINES THE PRECEPTS OF MEN.’ “
As an ending note:
It is a point to be made here that the keeping of The Seventh Day Sabbath> DOES NOT by itself make anyone a true disciple (follower) of God and His Christ- since there are many disobedient observers of this Holy Day. The Jews to this day do not recognize Jesus as The Messiah- yet they do recognize The Seventh Day of the week as The Lord’s Holy Sabbath. It should be noted here that God said that The Sabbath “is a sign between Me and My people“, He DID NOT say that It was THE sign that they are His people…
Aside from the topic of The Seventh Day Sabbath (and any works of The Law)- it is the willing heart of obedience, one that PRACTICES ALL God’s holy Commandments in their life through the FAITH and LOVE of God that are in Jesus Christ, His Messiah. This ATTITUDE OF OBEDIENCE TOWARD GOD, along with the firm reliance on God’s own chosen Messiah (Jesus Christ) as the sacrifice that leads to the forgiveness of any momentary failings in obedience (- Sin)…
1 John 2:1-6 (KJV)
My little children, these things write I unto you, that ye sin not. And IF any man sin, we have an advocate with the Father, Jesus Christ the righteous:  And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.  And hereby we do know that we know him, if we keep his commandments.  He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.  But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
 He that saith he abideth in him ought himself also so to walk, even as he walked.
It is the heart and mind-set for the “Repentance from Sin” (“sin is the transgression of The Law“- 1 John 3:4), and TURNING ourselves TO PRACTICE OBEDIENCE TO “The Truth” (“The Word of God“- the Word being THE tool through which our belief and obedience to It will work “sanctification“)– THESE are the things that decide whether a person is a member of “The Israel of God” as Paul refers to The Church.
Yet, works of Obedience can never be separated from this mindset of repentance from “Sin” (transgression of God’s Law)- since they are the results of The Love of The Truth and The Love of God that we have THROUGH Jesus Christ:
1 John 5:3 (KJV)
For THIS is the love of God, that we keep his commandments: and his commandments are not grievous.
James 2:26 (KJV)
For as the body without the spirit is dead, so Faith WITHOUT WORKS IS DEAD also.
Romans 8:39 (KJV)
…nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, WHICH IS IN Christ Jesus our Lord.
And, once more:
Galatians 5:6 (NASB)
For IN CHRIST JESUS neither circumcision nor uncircumcision means anything, but faith WORKING THROUGH love.
