8. But even if we (or an angel from heaven) should preach a gospel contrary to the one we preached to you, let him be condemned to hell!
9. As we have said before, and now I say again, if any one is preaching to you a gospel contrary to what you received, let him be condemned to hell!
10. Am I now trying to gain the approval of people, or of God? Or am I trying to please people? If I were still trying to please people, I would not be a slave of Christ!
11. Now I want you to know, brothers and sisters, that the gospel I preached is not of human origin.
12. For I did not receive it or learn it from any human source; instead I received it by a revelation of Jesus Christ.
13. For you have heard of my former way of life in Judaism, how I was savagely persecuting the church of God and trying to destroy it.
14. I was advancing in Judaism beyond many of my contemporaries in my nation, and was extremely zealous for the traditions of my ancestors.
15. But when the one who set me apart from birth and called me by his grace was pleased
16. to reveal his Son in me so that I could preach him among the Gentiles, I did not go to ask advice from any human being,
17. nor did I go up to Jerusalem to see those who were apostles before me, but right away I departed to Arabia, and then returned to Damascus.
18. Then after three years I went up to Jerusalem to visit Cephas and get information from him, and I stayed with him fifteen days.
19. But I saw none of the other apostles except James the Lord’s brother.
