What was the Gospel of Jesus Christ?
The Doctrinal Teaching of Jesus Christ
( “The Way of The Lord” )
It is routinely taught that The Gospel of Jesus Christ is “the good news” (literally “good message“) about The Kingdom of God coming, and of Salvation… This is only a partial truth about our Lord’s message. A key part to The Gospel of Jesus Christ is quite frequently overlooked, and altogether ignored in today’s preaching and ministry to people.
This study examines the original, and complete, “Gospel of The Kingdom”- as taught by our Lord and Savior, Jesus Christ (lit.- Joshua, Messiah).
– The Good Message
The first mention of our Lord’s appearance with a message to preach to the people is just after John Baptist’s arrest. This marks the moment when Jesus began His witness and prophetic ministry…
Notice what is said:
Matthew 4:17 (KJV)
…From that time Jesus began to preach, and to say, “Repent: for the kingdom of heaven is at hand.”
Jesus didn’t just preach ‘the good news’ that The Kingdom of God was coming and that better things were on the way through Salvation in His Name.
If one reads The Bible, they cannot fail to notice that, while He did speak about those things as part of The Good Message, He always taught along-side-of that the requirement to repent’ from sin, in order to be accepted into that coming Kingdom:
First- let’s look at the Biblical definition of “Sin” that God displays for us:
-(What is “Sin“?)
“Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.” – 1 John 3:4
Now, notice the meaning of “Repent“:
Repent- Strong’s Dictionary: metanoeo, Greek 3340, Strong’s
metanoeo, met-an-o-eh’-o; from Greek 3326 (meta) and Greek 3539 (noieo); to think differently or afterwards, i.e. reconsider (moral feel compunction) :- repent.
-(Compunction: A feeling of deep regret (usually for some misdeed)
Repent- NASB Dictionary:
metanoeo, Greek 3340; from Greek 3326 (meta) and Greek 3539 (noeo); to change one’s mind or purpose
There are many example of ‘repentance’ throughout The Bible for us to learn from…
Here are two examples of “Repentance” as defined by God:
Jonah 3:5-9 (KJV)
So the people of Nineveh believed God, and proclaimed a fast, and put on sackcloth, from the greatest of them even to the least of them.  For word came unto the king of Nineveh, and he arose from his throne, and he laid his robe from him, and covered him with sackcloth, and sat in ashes.
 And he caused it to be proclaimed and published through Nineveh by the decree of the king and his nobles, saying, Let neither man nor beast, herd nor flock, taste any thing: let them not feed, nor drink water:  But let man and beast be covered with sackcloth, and cry mightily unto God: yea, let them turn every one from his evil way, and from the violence that is in their hands.
 Who can tell if God will turn and repent, and turn away from his fierce anger, that we perish not?
2 Cor. 7:9-11 (KJV)
Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing.  For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
 For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what vehement desire, yea, what zeal, yea, what revenge! In all things ye have approved yourselves to be clear in this matter.
Back to what Jesus taught. Our Lord taught that all people should “repent” from SIN – (to “turn away from” sin)… As we see from the definition of the word “repent“- this is done by a person “changing one’s mind” toward sin in their day-to-day living.
Notice that Jesus didn’t leave it at merely turn away from Sin, but He also taught what a person should then turn TO. He preached that people should turn to the way-of-living that honors and respects The Father’s household rules… Jesus taught the necessary obedience to The Ten Commandment– while at the same time proclaiming that salvation would come through Faith in The Messiah that God Himself provides…Faith in Grace of God through His Messiah’s sacrifice- faith in the ability to be forgiven of Sin when sin is repented of.
The Scriptures show that Jesus called for people to obey (to practice The Father’s rules and standards for right and wrong)…
Jesus taught for people to stop disobeying God, and to begin trying to obey The Ten Commandments of His Father in their lives through sincere faith and love:
John 4:22-24 (KJV)
Ye worship ye know not what: we know what we worship: for salvation is of the Jews.
 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
 God is a Spirit: and they that worship him must worship him in spirit and in truth.
As for The worship of God “in” the Spirit –
2 Cor. 3:17, NASB
“The Lord is The Spirit”
John 14:20-24 (NASB)
“In that day you shall know that I am in My Father, and you IN Me, and I in you.
 “He who has My commandments AND KEEPS THEM, he it is who loves Me; and he who loves Me shall be loved by My Father, and I will love him, and will disclose Myself to him.”
 Judas (not Iscariot) said to Him, “Lord, what then has happened that You are going to disclose Yourself to us, and not to the world?”
 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.
2 Cor. 13:5 (NASB)
“…Jesus Christ is in you– unless indeed you fail the test”
******* (For more on this, see the study: “WHAT is The Holy Spirit?- What The Truth Says About God’s Power” )
So, one MUST worship God WHILE abiding “IN” Jesus Christ (which is The Faith that saves)…
Jesus confirmed this in His own words:
John 10:9 (KJV)
I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
Luke 10:22 (KJV)
All things are delivered to me of my Father: and no man knoweth who the Son is, but the Father; and who the Father is, but the Son, and he to whom the Son will reveal him.
John 10:1 (NASB)
“Truly, truly, I say to you, he who does not enter by the door into the fold of the sheep, but climbs up some other way, he is a thief and a robber.
Notice Jesus points out that if any man tries to enter The Kingdom any other way, except by being found to be IN Him, then he “is a thief and a robber”?…
Returning to Jesus’ message about the true worshippers of God (or rather ‘the sincere’ worshipping of God)- notice what Jesus also said about how they worship God,
“…they that worship him must worship him in spirit AND in Truth”
God and Jesus both define what “Truth” is for all to see:
John 17:17 (KJV)
Sanctify them through thy truth: thy word is truth.
Psalm 119:160 (KJV)
Thy word is true from the beginning: and every one of thy righteous judgments endureth for ever.
Notice that the Psalm says God’s righteous judgments “endure forever”?
Look at Paul’s words:
Romans 7:12 (NASB)
So then, The Law is holy, and the commandment is holy and righteous and good.
– ( remembering here that, “sin is the transgression of the law” )
Now, notice what Jesus Christ (The Lord of Christianity) clearly said about His Father’s Law:
Matthew 5:17-20 (NASB)
“Do not think that I came to abolish the Law or the Prophets; I did not come to abolish, but to fulfill.
 “For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass away from the Law, until all is accomplished.
 “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.
1 John 3:7-8 (NASB)
Little children, let no one deceive you; the one who practices righteousness is righteous, just as He is righteous;  the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, that He might destroy the works of the devil.
Now, notice what Jesus TAUGHT that the lawyer should do, IN ORDER TO ENTER into life with God (eternal life)- in reading this, please take note that there are in fact STIPULATIONS for receiving salvation:
Matthew 19:17 (NASB)
And He said to him, “Why are you asking Me about what is good? There is only One who is good; but if you wish to enter into life, keep the commandments.”
And again, to a lawyer that tested Him, He says:
Luke 10:25-28 (KJV)
And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life?
 He said unto him, What is written in the law? how readest thou?
 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
 And he said unto him, Thou hast answered right: this do, and thou shalt live.
The lawyer answered by presenting TWO points about The Law of God– not just love toward your neighbor, but also (and first and foremost) the love toward God…
Jesus’ response was perfectly clear- he said that the lawyer had “answered right” and told him that he would have “life” if he practiced THESE TWO THINGS in his life…
Jesus Himself clearly tells us what “the foremost” (or the most important) “Commandment” is in The Law:
Matthew 22:37-38 (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.
Couple these statements from our Lord (The Lord and instructor of true Christianity)– couple His statements above with what the apostle John presents to us as the defining of “The Love of God” and “The Love of Neighbor”:
1 John 5:2-3 (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.
Notice the proof of Love?……The one thing that reveals the fact that a person does indeed have The Love of God for God and his neighbor? The Keeping (or- the practice) of God’S commandments in day-to-day life.
Whether it be love toward our neighbor, OR love toward God The Father, our OBEDIENCE to God’s “Commandments” are what prove our love.
It is also worth pointing out that IF our obedience to God’s Commandments are what prove our love for our brother-in-Christ (the children of God), then such is also the case when it comes to the proof of our love for Jesus Christ (The Child of God)…
As the Apostle to the gentile believers, saint Paul presents this same message to the gentiles- that Obedience to “The Ten Commandments” is the evidence that the person does in fact have this “LOVE of God” abiding in them:
Romans 13:9-12 (NASB)
For THIS, “You shall NOT COMMIT ADULTERY, You shall NOT MURDER, You shall NOT STEAL, You shall NOT COVET,” and if there is any other commandment, it is summed up in this saying, “You shall love your neighbor as yourself.”
 Love does no wrong to a neighbor; love therefore is the fulfillment of the law.
 And this do, knowing the time, that it is already the hour for you to awaken from sleep; for now salvation is nearer to us than when we believed.  The night is almost gone, and the day is at hand. Let us therefore lay aside the deeds of darkness and put on the armor of light.
The Gospel of Christ IS “The Gospel of your salvation” (or “Good News of Your Salvation”)
Ephes. 1:12-14 (KJV)
That we should be to the praise of his glory, who first trusted in Christ.  In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,  Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
For more on the topic of Being Sanctified because of (or by) our Love of “The Truth”, refer to the study: “Sanctified By The Love of The Truth”
Paul preaches that “REPENTANCE” is a basic part of the foundational doctrines that are taught when it comes to learning about Jesus Christ and the life of a Christian:
Hebrews 6:1-2 (NASB)
Therefore leaving the elementary teaching about the Christ, let us press on to maturity, not laying again a foundation of repentance from dead works and of faith toward God,  of instruction about washings, and laying on of hands, and the resurrection of the dead, and eternal judgment.
He points out that one of the foundational rules that we are to build our Christian life upon is “REPENTANCE From Dead Works“…
He also clearly taught WHAT “dead works” are (works that lead to death):
Galatians 5:19-21 (KJV)
Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,  Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,  Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
And he teaches us that THAT repentance from dead works is “NOT to be repented of” (in other words, never turned back from):
2 Cor. 7:9-11 (KJV)
Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing.  For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.  For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what vehement desire, yea, what zeal, yea, what revenge! In all things ye have approved yourselves to be clear in this matter.
Galatians 2:17-18 (KJV)
But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid.  For if I build again the things which I destroyed, I make myself a transgressor.
– Our “REPENTANCE” Prepares the Mind For Serving God “In Sincerity & Truth”…
God’s Word says that John Baptist was the prophet that was to come before The Messiah, in order, “to prepare The Way of The Lord“…to, “make His paths straight“…
John Baptist taught people “The Way of The Lord”, just as Jesus would do when He came.
John was merely preparing peoples’ minds for what was coming… The Kingdom of Jesus Christ- “salvation” through a sincerity that is shown by repentance from sin, and by turning to practice obedience to The Truth.
Mark 1:1-5 (KJV)
The beginning of the gospel of Jesus Christ, the Son of God;  As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee.  The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
 John did baptize in the wilderness, and preach the baptism of repentance for the remission of sins.
 And there went out unto him all the land of Judaea, and they of Jerusalem, and were all baptized of him in the river of Jordan, confessing their sins.
Again, this is the same exact message (doctrinal teaching) that Jesus would preach after John- “REPENT“, so that you CAN BE “forgiven” (repentance FOR remission of Sins)… So that there can be the remissions (blotting out) of your sins- atonement made, or reconciliation worked between you and God…
John Baptist was said to be sent by God to “PREPARE The Way of The Lord” (The Way of God) before Jesus Christ came to preach and to minister… The Bible says that he was sent to “make His paths straight” (the paths of “The Lord”) … this meant- just as The bible says- that he was sent TO TURN the people’s hearts and minds away from the crooked and wrong way, in order to TURN the people’s hearts and minds to The Way that is acceptable and pleasing to The God of Israel (also The Father of Jesus Christ)…
To turn the people’s heart and mind away from “sin” (to cause “repentance“), in order to follow “The Way of The Lord”:
Luke 1:13-17 (KJV)
But the angel said unto him, Fear not, Zacharias: for thy prayer is heard; and thy wife Elisabeth shall bear thee a son, and thou shalt call his name John.  And thou shalt have joy and gladness; and many shall rejoice at his birth.  For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother’s womb.  And many of the children of Israel shall he turn to The Lord their God.
 And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord.
John Baptist’s father was prophesying here. He was pointing out that The Sacred Scripture was in the process of being fulfilled at that time…
Here is the Scripture that John’s father was referring to:
Malachi 3:1 (KJV)
Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant……
…….. “Behold, I am going to send you Elijah the prophet before the coming of the great and terrible day of the Lord.  And he will restore the hearts of the fathers to their children, and the hearts of the children to their fathers, lest I come and smite the land with a curse.”
Notice “The Way of The Lord” is defined in what we just read in Luke- it is right there for all to see:
to turn to (or toward) The Lord (Obedience to His Way, His definition of right-living)…
to turn the heart to (or toward) The Father…
To turn the DISOBEDIENT to (or toward) “the wisdom of the just”— or, as the New American Standard Bible translates it, to turn the disobedient “to the attitude of the righteous; so as to make ready a people prepared for the Lord.“
Simply put, this is all identical to the message that Jesus preached, and that message is summed up in The Lord’s first words of His ministry:
“REPENT, for the kingdom of heaven is at hand!”
The simple truth is that it is our very commitment to the “REPENTANCE from dead works” that allows God to work with us… It allows for Him to send His Holy Spirit into our hearts:
Acts 2:38 (KJV)
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, AND YE SHALL RECEIVE THE GIFT of the Holy Ghost.
Once again here we are shown the stipulations “FOR remission of sins“- (that we “repent and be baptized”)…
Notice that “repentance from dead works” is to be agreed to even before baptism? This is because of what Baptism represents in Christ Jesus:
Col. 2:10-13 (KJV)
And ye are complete in him, which is the head of all principality and power:  In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:  Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.
 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
Romans 6:1-4 (KJV)
What shall we say then? Shall we continue in sin, that grace may abound?……
Romans 6:15 (KJV)
What then? SHALL WE SIN, because we are not under the law, but under grace? God forbid.
……Shall we continue in sin, that grace may abound?  God forbid. How shall we, that are dead to sin, live any longer therein?
 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?  Therefore we are buried with him BY BAPTISM INTO DEATH: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
It can not be stressed enough that it is our repentance that allows God to work in us through Jesus Christ (our “mediator” and “intercessor”):
Galatians 4:6 (KJV)
And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
Repentance is a Permanent CHANGE of Lifestyle
The lifestyle of “repentance“- of turning the heart and mind to the attitude of obedience to The Law of God– THIS has been “The Way of The Lord” that has been taught from the beginning- it is the way that has been commanded to be followed by God from the beginning…
Repentance has been laid down by God (from the beginning) as a stipulation (a condition) for receiving “forgiveness” from our sins (which is “grace”)…
In this way God makes it clear that If a person does not prepare their mind and heart to repent before Him, then they will not receive The Grace that saves.
2 Kings 17:13 (NASB)
Yet The Lord warned Israel and Judah, through all His prophets and every seer, saying, “Turn from your evil ways and keep My commandments, My statutes according to all the law which I commanded your fathers, and which I sent to you through My servants the prophets.”
Ezekiel 33:11 (KJV)
Say unto them, “As I live, saith The Lord God, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn ye, turn ye from your evil ways; for why will ye die, O house of Israel?”
THIS stipulation has always been a major part of The Message that comes from God for how to be acceptable, and to be ONE with Him (to be His people)…
Jeremiah 24:7 (KJV)
And I will give them an heart to know me, that I am the Lord: and they shall be my people, and I will be their God: for they shall return unto me with their whole heart.
Jeremiah 31:31-34 (KJV)
Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
 But THIS shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward PARTS, and write it in their hearts; and will be their God, and they shall be my people.
 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord; for I will forgive their iniquity, and I will remember their sin no more.
FIRST, God says that He will put HIS LAW into their inward parts (their minds)…and it is THEN that He says, ” I will remember their sins no more“…
Psalm 119:11 (KJV)
THY WORD have I hid IN MINE HEART, that I might not sin against thee.
So again, what God says the covenant will based on?
“I will put MY LAW in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.”
“…they shall all know me, from the least of them unto the greatest of them, saith the Lord; for I will forgive their iniquity, and I will remember their sin no more.”
We are shown why this stipulation for a person to “REPENT“, in order to be accepted is such a major part of the “good message” that John Baptist preached in the statement that he was preparing the people’s hearts for “The Way of The Lord”…
Notice John’s words:
Luke 3:8-9 (NASB)
“…Therefore bring forth fruits in keeping with repentance, and do not begin to say to yourselves, ‘We have Abraham for our father,’ for I say to you that God is able from these stones to raise up children to Abraham.  “And also the axe is already laid at the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire.”
The reason for the stipulation to Repent is clear– because “every tree” that does not do it will be, “cut down and thrown into the fire”
– Please take Note of the similarity between Christian and Jew when it comes to how this attitude of repentance works… Just as it is with the Jews that claim righteousness and salvation as the people of God simply because they “have Abraham as father”- so it is for the Christian that claims they have righteousness and salvation because they have Christ, and yet does not OBEY what is written by God to do:
– The “Jew” who does not repent and turn to practice The way of life that is OBEDIENT to God’s Word (The Truth), will not be saved by confidence in Abraham
Matthew 3:8-9 (KJV)
…Bring forth therefore fruits meet for repentance:  And think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham.
Just as with the “Jew” who will not believe and turn- so it is with the “Christian” who will not repent and turn to practice a way of life that is obedient to God’s Word (The Truth) through their beliefs in Christ and God- such a person will not be saved by confidence in Christ Jesus; not without true repentance fist.
Matthew 25:41-42 (NASB)
“Then He will also say to those on His left, ‘Depart from Me, accursed ones, into the eternal fire which has been prepared for the devil and his angels;  for I was hungry, and you gave Me nothing to eat; I was thirsty, and you gave Me nothing to drink…
2 Thes. 1:7-10 (NASB)
…when the Lord Jesus shall be revealed from heaven with His mighty angels in flaming fire,  dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus.
 And these will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power,  when He comes to be glorified in His saints on that day, and to be marveled at among all who have believed– for our testimony to you was believed.
Compare this “Way of The Lord” to what Paul preached to the gentile believers in Corinth (remembering that The Church in Corinth did not consist of Jewish believers, yet Paul preached the way of OBEDIENCE TO THE LAW to them- even to them who were “under grace“):
1 Cor. 6:9-11 (KJV)
Know ye not that the unrighteous shall not inherit the kingdom of God?
Be not deceived:
NEITHER fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,  Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
 And such WERE some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, AND by the Spirit of our God.
Notice the use of the past-tense of the description of “you” here? …such “WERE” some of you…but, you HAVE repented and TURNED TO God through Christ…
And again, examining what it was that Paul preached to the gentile believers in Rome…GENTILE (non-Jew) Christians who were now “under grace”- Paul preached to them the same message of repentance and turning to practice obedience to ALL OF God’s Ten Commandments:
Paul says to these Gentile believers here in Rome:
Romans 6:14-22 (KJV)
[ “for sin is the transgression of the law.” – 1 John 3:4 ]
……For sin shall not have dominion over you: for ye are not under the law, but under grace.
 What then?
Shall we sin, because we are not under the law, but under grace?
Romans 3:8 (NASB)
…And why not say (as we are slanderously reported and as some affirm that we say), “Let us do evil that good may come”? Their condemnation is just.
……Shall we sin, because we are not under the law, but under grace?
Paul preached the same “good message” that John Baptist and Jesus taught- “REPENT, for the kingdom of heaven is at hand!”…
He continued here:
… Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, OR of obedience unto righteousness?
 But God be thanked, that ye WERE the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.
 Being then made free from sin, ye BECAME the servants of righteousness.
 I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so NOW yield your members servants to righteousness unto holiness.  For when ye were the servants of sin, ye were free from righteousness.  What fruit HAD ye THEN in those things whereof ye are NOW ashamed? for the end of those things is death.
 But NOW being made free from sin, and BECOME servants to God, ye have your fruit unto holiness, and the end everlasting life.
Look at Paul’s own testimony about “The Good Message” (Gospel) of salvation that he preached:
Acts 26:19-20 (NASB)
“Consequently, King Agrippa, I did not prove disobedient to the heavenly vision,  but kept declaring both to those of Damascus first, and also at Jerusalem and then throughout all the region of Judea, and even to the Gentiles, that they should repent AND turn to God, performing deeds appropriate to repentance.
So, we see that The Good Message of The Kingdom of God (The Gospel of Jesus Christ), is not merely The Good News about The Kingdom coming (i.e.- the kingdom, “is at hand“), but the good message MUST also contain The Way to enter into that coming Kingdom of God- which is The Calling for ALL people EVERYWHERE:
“REPENT” from Sin
TO TURN TO a lifestyle of obedience to God (“practicing” righteousness)
The true “Gospel of Jesus Christ” WILL NEVER neglect to teach and preach the stipulation that God Himself has laid down for any person to be allowed to enter (to be accepted) INTO that Kingdom!
This is why we encourage all everywhere to “repent” from practicing any way that is contrary to (“contradicts“- or, “denies“) what God’s Holy Word teaches…The Word of God being The Bible, containing The Law and Prophets, Jesus Christ and His Holy Apostles’ doctrinal teachings in Him.
This is would be why we exhort people to “turn away from” the practice of Sunday-keeping, and the practice of following man’s holidays instead of God’s Holy Days…and to turn away from the practice of following after a way of life that teaches that “sin” (the practice of disobedience to ANY of The Ten Commandments of God’s Law) can be allowed for, since one is “under grace”…They teach that one need ‘just believe, and you will be saved’- while Christ says through His servant James,
“You believe that God is one. You do well; the demons also believe, and shudder. But are you willing to recognize, you foolish fellow, that faith without works is useless?” – James 2:19-20)
All of these teachings coming out of the many so-called-Christian churches are part of “A Lie” that has led astray the majority of people claiming to be in “Christ”!
Our Lord states clearly that, “No lie is of The Truth“… He also says to His Father (God of Israel), “Thy Word is Truth“… For these reasons, he who ‘contradicts’ (or “denies”) The Word of God when shown the way of life to live in order to be saved, ‘contradicts‘ (or “denies“) Jesus Christ, and is taking part with the way of an “anti-christ” faith…
“There are many anti-christs“, as James points out (- 2:18); the ways of “antichrists” are simply put: the ways of all who are living ‘against‘, or ‘contrary to‘ the doctrinal teaching of our Lord, Jesus Christ (The Lord of Christianity, and The Lord over the true “Israel of God”)… Such a person living in a faith that contradicts Jesus’ holy Doctrines cannot be reconciled to God UNLESS, or UNTIL, they “repent and turn to God, performing deeds appropriate to repentance“,
Luke 13:3 (NASB)
“I tell you, no, but unless you repent, you will all likewise perish…
Rev. 2:5 (NASB)
‘Remember therefore from where you have fallen, and repent and do the deeds you did at first; or else I am coming to you, and will remove your lampstand out of its place– unless you repent….
 ‘He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will grant to eat of the tree of life, which is in the Paradise of God.’
John 8:24 (NASB)
“I said therefore to you, that you shall die in your sins; for unless you believe that I am He, you shall die in your sins.”
Romans 10:10 (NASB)
…for with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
1 John 3:3-4 (KJV)
And every man that hath this hope in him purifieth himself, even as he is pure.  Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
Deut. 30:11-20 (NASB)
“For this commandment which I command you today is not too difficult for you, nor is it out of reach.  “It is not in heaven, that you should say, ‘Who will go up to heaven for us to get it for us and make us hear it, that we may observe it?’  “Nor is it beyond the sea, that you should say, ‘Who will cross the sea for us to get it for us and make us hear it, that we may observe it?’  “But the word is very near you, in your mouth and in your heart, that you may observe it.
 “See, I have set before you today life and prosperity, and death and adversity;  in that I command you today to love the Lord your God, to walk in His ways and to keep His commandments and His statutes and His judgments, that you may live and multiply, and that the Lord your God may bless you in the land where you are entering to possess it.  “But if your heart turns away and you will not obey, but are drawn away and worship other gods and serve them,  I declare to you today that you shall surely perish. You shall not prolong your days in the land where you are crossing the Jordan to enter and possess it.
 “I call heaven and earth to witness against you today, that I have set before you life and death, the blessing and the curse. So choose life in order that you may live, you and your descendants,  by loving the Lord your God,
1 John 5:3 (KJV)
For this is the love of God, that we keep his commandments: and his commandments are not grievous.
by obeying His voice, and by holding fast to Him; for this is your life and the length of your days, that you may live in the land which the Lord swore to your fathers, to Abraham, Isaac, and Jacob, to give them.”
