Romans 2:25-29 - Circumcision Of The Heart
25 For circumcision indeed is profitable if you perform the law, but if you are a transgressor of the law, your circumcision becomes uncircumcision. 26 If therefore the uncircumcision keeps the ordinances of the law, shall not its uncircumcision be accounted for circumcision? 27 And the uncircumcision by nature which keeps the law shall judge you who with the written law and circumcision are a transgressor of the law. 28 For not that which is external is the Jew, nor is that which is external in the flesh circumcision. 29 But that which is in secret is the Jew, and circumcision of the heart is in the spirit not in the writing, the commendation of which is not of men but of God.
