Really? How did this escape them?
No Other Gospel
6 I am astonished that you are so quickly deserting the one who called you to live in the grace of Christ and are turning to a different gospel 7 which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. 8 But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under Gods curse! 9 As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let them be under Gods curse!
How can you escape God's curse?
