Galatians 5:1-4

1It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery. 2Mark my words! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. 3Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law. 4You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace.
