6 I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel, 7 which is not just another account; but there are some who are disturbing you and want to distort the gospel of Christ. 8 But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! 9 As we have said before, even now I say again: if anyone is preaching to you a gospel contrary to what you received, he is to be accursed!
10 For am I now seeking the favor of people, or of God? Or am I striving to please people? If I were still trying to please people, I would not be a bond-servant of Christ.
11 For I would have you know, brothers and sisters, that the gospel which was preached by me is not of human invention.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 way 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 He 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.
