2 Corinthians 5:17

Therefore if any man is in Christ, he is a new creature; the old things passed away; behold new things have come.

Colossians 3:10-11

And have put on the new self who is being renewed to a true knowledge according to the image of the One who created him -- a renewal in which there is no distinction between Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave and freeman, but Christ is all, and in all.

Galatians 6:14-16

But may it never be that I should 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.
