'Uncircumcised' in the Bible

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

since indeed there is one God who will justify the circumcised by faith, and the uncircumcised through faith.

Is this blessing then pronounced on the circumcised, or on the uncircumcised also? For we say that faith was accounted to Abraham for righteousness.
