Galatians 5:2-6

2Take notice: I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. 3Again I testify to every man who gets himself circumcised that he is obligated to obey the whole law. 4You who are trying to be justified by the law have been severed from Christ; you have fallen away from grace.

5But by faith we eagerly await through the Spirit the hope of righteousness. 6For in Christ Jesus neither circumcision nor uncircumcision has any value. What matters is faith expressing itself through love.
