Romans 2:25-29

Amplified Bible, Classic Edition

²⁵ Circumcision does indeed profit if you keep the Law; but if you habitually transgress the Law, your circumcision is made uncircumcision.

²⁶ So if a man who is uncircumcised keeps the requirements of the Law, will not his uncircumcision be credited to him as [equivalent to] circumcision?

²⁷ Then those who are physically uncircumcised but keep the Law will condemn you who, although you have the code in writing and have circumcision, break the Law.

²⁸ For he is not a [real] Jew who is only one outwardly and publicly, nor is [true] circumcision something external and physical.

²⁹ But he is a Jew who is one inwardly, and [true] circumcision is of the heart, a spiritual and not a literal [matter]. His praise is not from men but from God.
