Romans 2:25-29 Circumcision does indeed profit, if you obey the Law; but if you are a Law-breaker, the fact that you have been circumcised counts for nothing.

WNT⁽ⁱ⁾ ²⁵ Circumcision does indeed profit, if you obey the Law; but if you are a Law-breaker, the fact that you have been circumcised counts for nothing. ²⁶ In the same way if an uncircumcised man pays attention to the just requirements of the Law, shall not his lack of circumcision be overlooked, and, ²⁷ although he is a Gentile by birth, if he scrupulously obeys the Law, shall he not sit in judgement upon you who, possessing, as you do, a written Law and circumcision, are yet a Law-breaker? ²⁸ For the true Jew is not the man who is simply a Jew outwardly, and true circumcision is not that which is outward and bodily. ²⁹ But the true Jew is one inwardly, and true circumcision is heart-circumcision--not literal, but spiritual; and such people receive praise not from men, but from God.
