Therefore if the uncircumcised keep the right things contained in the law: shall not his uncircumcision be counted for circumcision?

For he is not a Jew, which is a Jew outward. Neither is that thing circumcision, which is outward in the flesh: But he is a Jew which is hid within, and the circumcision of the heart is the true circumcision, which is in the spirit, and not in the letter: whose praise is not of men but of God.
