Galatians 5:2-5
5:2 Listen! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no benefit to you at all!
5:3 And I testify again to every man who lets himself be circumcised that he is obligated to obey the whole law.
5:4 You who are trying to be declared righteous by the law have been alienated from Christ; you have fallen away from grace!
5:5 For through the Spirit, by faith, we wait expectantly for the hope of righteousness.
