Galatians 5:3–6

3 I testify again to every man who receives circumcision that he is bound to keep the whole law. 4 You are severed from Christ, you who would be justified by the law; you have fallen away from grace. 5 For through the Spirit, by faith, we wait for the hope of righteousness. 6 For in Christ Jesus neither circumcision nor uncircumcision is of any avail, but faith working through love.
