6 I am surprised at you! In no time at all you are deserting the one who called you by the grace of Christ, and are accepting another gospel.
7 Actually, there is no “other gospel”, but I say this because there are some people who are upsetting you and trying to change the gospel of Christ.
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.
