'Uncircumcision' in the Bible

For circumcision has its value if you practice the law, but if you break the law, your circumcision has become uncircumcision.

Therefore if the uncircumcised man obeys the righteous requirements of the law, will not his uncircumcision be regarded as circumcision?

Is this blessedness then for the circumcision or also for the uncircumcision? For we say, "faith was credited to Abraham as righteousness."
