Romans 2:25-26

Amplified Bible

²⁵ Circumcision [the sign of the covenant of Abraham] is indeed of value if you practice the Law; but if you habitually break the Law, your circumcision has become uncircumcision [it is meaningless in God’s sight]. ²⁶ So if the uncircumcised man keeps the requirements of the Law, will not his uncircumcision be regarded [by God] as circumcision?
