'Uncircumcision' in the Bible

For circumcision indeed profits, if you are a doer of the law, but if you are a transgressor of the law, your circumcision has become uncircumcision.

If therefore the uncircumcised keep the ordinances of the law, won't his uncircumcision be accounted as circumcision?

Won't the uncircumcision which is by nature, if it fulfills the law, judge you, who with the letter and circumcision are a transgressor of the law?

How then was it counted? When he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision.

He received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision, that he might be the father of all those who believe, though they might be in uncircumcision, that righteousness might also be accounted to them.

He is the father of circumcision to those who not only are of the circumcision, but who also walk in the steps of that faith of our father Abraham, which he had in uncircumcision.
