Galatians 5:1, 3-4

At last we have freedom, for Christ has set us free! We must always cherish this truth and firmly refuse to go back into the bondage of our past.

I say it again emphatically: If you let yourselves be circumcised you are obliged to fulfill every single one of the commandments and regulations of the law! If you want to be made right with God by fulfilling the obligations of the law, you have cut off more than your flesh—you have cut yourselves off from Christ and have fallen away from the revelation of grace!
