Act 17:30 The times of ignorance God overlooked, but now he commands all people everywhere to repent, (ESV)
Paul speaking to he Athenians at the Areopagus; most certainly not believers.
Act 26:19 "Therefore, O King Agrippa,
I was not disobedient to the heavenly vision,
Act 26:20 but
declared first to those in Damascus, then in Jerusalem and throughout all the region of Judea, and also to the Gentiles, that they should repent and turn to God, performing deeds in keeping with their repentance. (ESV)
Again, this is Paul, clearly speaking to non-believers.
There has only ever been one Gospel and both Peter and Paul preached it, along with the rest of the Apostles and early church. And that is consistent with what Jesus taught.
When I talk about Pauls revelation, I'm not talking about his conversion.
Gal. 1:11-12
11 But I certify you, brethren, that the gospel which was preached of me is not after man.
12 For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.
Gal. 1:15-16
15 But when it pleased God, who separated me from my mother's womb, and called me by his grace,
16 To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:
Scriptures you quote are before his revelation. After Pauls revelation you will not find where he tells the sinner to repent. I'm not preaching against it most of us come to God based on repenting and being baptized, I know I did.
Paul came to a point where he would not baptize anyone.
I'm saying it is not scriptural in the age of pure grace now.
To me that is why Paul is so important to the born again, we get sound doctrine.
Eph. 3:1-9
3 For this cause I Paul, the prisoner of Jesus Christ for you Gentiles,
2 If ye have heard of the dispensation of the grace of God which is given me to you-ward:
3 How that by revelation he made known unto me the mystery; (as I wrote afore in few words,
4 Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)
5 Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;
6 That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
7 Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power.
8 Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ;
9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
