8. But even if we or an angel from heaven should preach to you a gospel that is different from the one we preached to you, may he be condemned to hell!
9. We have said it before, and now I say it again: if anyone preaches to you a gospel that is different from the one you accepted, may he be condemned to hell!
10. Does this sound as if I am trying to win human approval? No indeed! What I want is God's approval! Am I trying to be popular with people? If I were still trying to do so, I would not be a servant of Christ.
11. Let me tell you, my brothers and sisters, that the gospel I preach is not of human origin.
12. I did not receive it from any human being, nor did anyone teach it to me. It was Jesus Christ himself who revealed it to me.
13. You have been told how I used to live when I was devoted to the Jewish religion, how I persecuted without mercy the church of God and did my best to destroy it.
