Galatians 5:2-11

2Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing. 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.

7Ye did run well; who did hinder you that ye should not obey the truth? 8This persuasion cometh not of him that calleth you. 9A little leaven leaveneth the whole lump. 10I have confidence in you through the Lord, that ye will be none otherwise minded: but he that troubleth you shall bear his judgment, whosoever he be. 11And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.
