he preached repentance and faith in God preached the same gospel and his teachings should never be thrown out nor should anyone throw out the gospel and follow Paul as messiah
Paul preached the gospel of the kingdom of God including repentance and faith the same message tinker and gentile
“And how I kept back nothing that was profitable unto you, but have shewed you, and have taught you publickly, and from house to house, Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ.
And now, behold, I know that ye all, among whom I have gone preaching the kingdom of God, shall see my face no more.”
Acts 20:20-21, 25
Paul actually taught more about sin it’s consequences and repentance than Moses law did.
while we take a statement like “ grace” and “ election “ out of the scripture it exists in its easily distorted Paul’s election includes this instruction
“This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
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.”
Galatians 5:16, 19-21 KJV
Paul preached about inheriting the kingdom but also warned of the consequences of sin . To show this is a constant in his doctrine
“But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints; Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks.
For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.
Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience. Be not ye therefore partakers with them.”
Ephesians 5:3-7 KJV
Paul’s message is urgent about repenting from sin and walking in the spirit with the lord
“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.”
1 Corinthians 6:9-10 KJV
Those are a few examples of Paul’s doctrine other than the catch phrases we hear like “ saved by grace” election isn’t the end , faith is the end
