Galatians 5:1-4

It is for freedom that Christ has set us free. Stand firm, then, and do not be encumbered once more by a yoke of slavery.

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

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.
