Galatians 6:13-16

For those who are circumcised do not even keep the Law themselves, but they desire to have you circumcised so that they may boast in your flesh. But may it never be that I would boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world. For neither is circumcision anything, nor uncircumcision, but a new creation. And those who will walk by this rule, peace and mercy be upon them, and upon the Israel of God.
