Galatians 5:2-4

Listen! I, Paul, tell you this: If you are counting on circumcision to make you right with God, then Christ will be of no benefit to you. I’ll say it again. If you are trying to find favor with God by being circumcised, you must obey every regulation in the whole law of Moses. For if you are trying to make yourselves right with God by keeping the law, you have been cut off from Christ! You have fallen away from God’s grace.
