Romans 2:23-29

23You who boast in the law dishonor God by transgressing the law!

24For just as it is written, “the name of God is being blasphemed among the Gentiles because of you.”

25For circumcision has its value if you practice the law, but if you break the law, your circumcision has become uncircumcision.

26Therefore if the uncircumcised man obeys the righteous requirements of the law, will not his uncircumcision be regarded as circumcision?

27And will not the physically uncircumcised man who keeps the law judge you who, despite the written code and circumcision, transgress the law?

28For a person is not a Jew who is one outwardly, nor is circumcision something that is outward in the flesh,

29but someone is a Jew who is one inwardly, and circumcision is of the heart by the Spirit and not by the written code. This person’s praise is not from people but from God.
