11 For I would have you know, 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 I received it through a revelation of Jesus Christ. 13 For you have heard of my former manner of life in Judaism, how I used to persecute the church of God beyond measure and tried to destroy it; 14 and I was advancing in Judaism beyond many of my contemporaries among my countrymen, being more extremely zealous for my ancestral traditions. 15 But when God, who had set me apart even from my mother's womb and called me through His grace, was pleased 16 to reveal His Son in me so that I might preach Him among the Gentiles, I did not immediately consult with flesh and blood, 17 nor did I go up to Jerusalem to those who were apostles before me; but I went away to Arabia, and returned once more to Damascus.
18 Then three years later I went up to Jerusalem to become acquainted with Cephas, and stayed with him fifteen days. 19 But I did not see any other of the apostles except James, the Lord's brother. 20 (Now in what I am writing to you, I assure you before God that I am not lying.) 21 Then I went into the regions of Syria and Cilicia. 22 I was still unknown by sight to the churches of Judea which were in Christ; 23 but only, they kept hearing, "He who once persecuted us is now preaching the faith which he once tried to destroy." 24 And they were glorifying God because of me.
