Galatians 5:3-6

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. 5:6 For in Christ Jesus neither circumcision nor uncircumcision carries any weight – the only thing that matters is faith working through love.
