“For he is not a Jew who is one outwardly, neither is that circumcision which is outward in the flesh;”
Romans 2:28 (WEB)
Context Reading
26If therefore the uncircumcised keep the ordinances of the law, won’t his uncircumcision be accounted as circumcision? 27Won’t those who are physically uncircumcised, but fulfill the law, judge you, who with the letter and circumcision are a transgressor of the law? 28For he is not a Jew who is one outwardly, neither is that circumcision which is outward in the flesh; 29but 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 from men, but from God.
