Galatians 1:9

1:9 As we have said before, and now I say again, if any one is preaching to you a gospel contrary to what you received, let him be condemned to hell!

Galatians 3:15-16

Inheritance Comes from Promises and not Law

3:15 Brothers and sisters, I offer an example from everyday life: When a covenant has been ratified, even though it is only a human contract, no one can set it aside or add anything to it. 3:16 Now the promises were spoken to Abraham and to his descendant. Scripture does not say, “and to the descendants,” referring to many, but “and to your descendant,” referring to one, who is Christ.

Galatians 6:8

6:8 because the person who sows to his own flesh will reap corruption from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit.
