Galatians 5:2-4

2Listen carefully! I, Paul, tell you this. If you agree that someone should circumcise you, then Christ will be worth nothing to you.

3I will say it very clearly. Every man who lets someone circumcise him must then obey all the Jewish rules.

4I say this to you people who try to obey the rules of God's Law. If you think that God will accept you as right because you do that, you have turned away from Christ. You no longer agree to accept God's kind gift.
