Galatians 6:11-15

See with what large letters I am writing to you with my own hand. Those who desire to make a good showing in the flesh try to compel you to be circumcised, simply so that they will not be persecuted for the cross of Christ. 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.
