Circumcision: A Seal of Righteousness
Source: Nav
Romans 2:25–29
Circumcision has value if you observe the law, but if you break the law, your circumcision has become uncircumcision. / If a man who is not circumcised keeps the requirements of the law, will not his uncircumcision be regarded as circumcision? / The one who is physically uncircumcised yet keeps the law will condemn you who, even though you have the written code and circumcision, are a lawbreaker.
Romans 4:11
And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but are not circumcised, in order that righteousness might be credited to them.
