Galatians 5:3-6

3For I testify again to every man that is circumcised, that he is a debtor to do the whole law.

4Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.

5For we through the Spirit wait for the hope of righteousness by faith.

6For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
