Thematic Bible: Whose circumcision is made uncircumcision

For circumcision is valuable if you observe the Law, but if you break the Law, your having been circumcised has no more value than if you were uncircumcised. So if a man who is uncircumcised keeps the requirements of the Law, his uncircumcision will be regarded as circumcision, won't it? The man who is uncircumcised physically but who keeps the Law will condemn you who break the Law, even though you have the written Law and circumcision.
