Romans 2:25-29 - Circumcision Of The Heart
25 For circumcision indeed profits, if you do the law: but if you be a transgressor of the law, your circumcision has become uncircumcision. 26 Then if uncircumcision may keep the righteousness of the law, will not his uncircumcision be counted for circumcision? 27 and that which is uncircumcision by nature, perfecting the law, will judge you, who through the letter and circumcision are a transgressor of the law. 28 For he is not a Jew who is one outwardly; neither is circumcision that which is outwardly in the flesh. 29 But he is a Jew, who is one inwardly; and circumcision is that of the heart, in the spirit, not in the letter; whose praise is not of men, but of God.
