Galatians 5:4

² Take notice: I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all.

³ Again I testify to every man who gets himself circumcised that he is obligated to obey the whole law.

You who are trying to be justified by the law have been severed from Christ; you have fallen away from grace.

⁵ But by faith we eagerly await through the Spirit the hope of righteousness.

⁶ For in Christ Jesus neither circumcision nor uncircumcision has any value. All that matters is faith, expressed through love.

Do read the surrounding verses too, because the context often says more than a single verse.
