Galatians 1

v.4

v.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.

v.8-9

But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned! ⁹As 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 God’s curse!

v.10

Am I now trying to win the approval of human beings, or of God? Or am I trying to please people? If I were still trying to please people, I would not be a servant of Christ.

v.11-12

I want you to know, brothers, that the gospel I preached is not something that man made up. ¹²I did not receive it from any man, nor was I taught it; rather, I received it by revelation from Jesus Christ.

v.20

I assure you before God that what I am writing you is no lie.

v.23

They only heard the report: “The man who formerly persecuted us is now preaching the faith he once tried to destroy.”
