Romans 2:25-29 NIV

[25] Circumcision has value if you observe the law, but if you break the law, you have become as though you had not been circumcised. [26] So then, if those who are not circumcised keep the law’s requirements, will they not be regarded as though they were circumcised? [27] The one who is not circumcised physically and yet obeys the law will condemn you who, even though you have the written code and circumcision, are a lawbreaker. [28] A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. [29] No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.
