Galatians 6:13-15

13Not even those who are circumcised keep the law, yet they want you to be circumcised that they may boast about your circumcision in the flesh. 14May I never boast except in the cross of our Lord Jesus Christ, through which Or whom the world has been crucified to me, and I to the world. 15Neither circumcision nor uncircumcision means anything; what counts is the new creation.
