Galatians 1:9-10

9 We have already said this, but now I will say it again. Do not accept any message that is different from the message that we taught you. If anyone teaches a different message, I pray that God will curse them for ever.

10 When I say these things, I am not trying to please people. No, it is God that I want to please. If I only wanted to make people happy, then I would not be a servant of Christ.
