Getting back to the secret God gave to Paul, when we read in the Bible about the wonderful Dispensation of Grace, we see it was hidden in God until He raised up the Apostle Paul and gave him the new message, a different gospel and dispensation from the one that He had given to Peter and the eleven, who preached the Gospel of the Circumcision.
At first, Paul alone, was given this Dispensation of Grace that was and never revealed before.
1 Cor 9:17,18 For if I do this willingly, I have a reward; but if against my will, I have been entrusted with a dispensation. 18 What is my reward then? That when I preach the gospel, I may present the gospel of Christ without charge, that I may not abuse my authority in the gospel.
Eph 3:1-4 For this reason I, Paul, the prisoner of Christ Jesus for you Gentiles; 2 if indeed you have heard of the Dispensation of the Grace of God which was given to me for you, 3 how that by revelation He made known to me the mystery as I have briefly written already, 4 by which, when you read, you may understand my knowledge in the mystery of Christ.
We find in Acts 15 that Paul went up to Jerusalem to tell them about the new gospel that God gave to him.
According to Gal 1:11-2:10. The Holy Spirit showed the apostles at that council, that this new gospel, Paul’s gospel, was valid.
Gal 1:11-2:10 But I make known to you, brethren, that the gospel which was preached by me is not according to man. 12 For I neither received it from man, nor was I taught it, but it came through the revelation of Jesus Christ. 13 For you have heard of my former conduct in Judaism, how I persecuted the church of God beyond measure and tried to destroy it. 14 And I advanced in Judaism beyond many of my contemporaries in my own nation, being more exceedingly zealous for the traditions of my fathers. 15 But when it pleased God, who separated me from my mother’s womb and called me through His grace, 16 to reveal His Son in me, that I might preach Him among the Gentiles, I did not immediately confer with flesh and blood, 17 nor did I go up to Jerusalem to those who were apostles before me; but I went to Arabia, (That was for 3 years, as we’ll see in the next verse.) and returned again to Damascus. 18 Then after three years I went up to Jerusalem to see Peter, and remained with him fifteen days. 19 But I saw none of the other apostles except James, the Lord’s brother. 20 (Now concerning the things which I write to you, indeed, before God, I do not lie.) 21 Afterward I went into the regions of Syria and Cilicia. 22 And I was unknown by face to the churches of Judea which were in Christ. 23 But they were hearing only, “He who formerly persecuted us now preaches the faith which he once tried to destroy.” 24 And they glorified God in me.
Chapter 2
Then after fourteen years I went up again to Jerusalem with Barnabas, and also took Titus with me. 2 And I went up by revelation, and communicated to them that gospel which I preach among the Gentiles, but privately to those who were of reputation, lest by any means I might run, or had run, in vain. 3 Yet not even Titus who was with me, being a Greek, was compelled to be circumcised. 4 And this occurred because of false brethren secretly brought in (who came in by stealth to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage), 5 to whom we did not yield submission even for an hour, that the truth of the gospel might continue with you. 6 But from those who seemed to be something - whatever they were, it makes no difference to me; God shows personal favoritism to no man - for those who seemed to be something added nothing to me. 7 But on the contrary, when they saw that the gospel of the uncircumcision had been committed to me, as the gospel of the circumcision was to Peter 8 (for He who worked effectively in Peter for the apostleship of the circumcision also worked effectively in me toward the Gentiles), 9 and when James, Cephas, and John, who seemed to be pillars, perceived the grace that had been given to me, they gave me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcision.
