Romans 2:25-29

25Circumcision is indeed worthwhile if you keep the Torah; but if you break the Torah, your circumcision has become uncircumcision.

26Therefore, if the uncircumcised keeps the righteous decrees of the Torah, will not his uncircumcision be counted as circumcision?

27Indeed, the one not circumcised physically who fulfills the Torah will judge you who—even with the written code and circumcision—break the Torah.

28For one is not a Jew who is one outwardly, nor is circumcision something visible in the flesh.

29Rather, the Jew is one inwardly, and circumcision is of the heart—in Spirit not in letter. His praise is not from men, but from God.
