Romans 2
23 Ref You who glory in the law, through your disobedience of the law do you dishonor God?
24 Ref For "the name of God is blasphemed among the Gentiles because of you," just as it is written.
25 Ref For circumcision indeed profits, if you are a doer of the law, but if you are a transgressor of the law, your circumcision has become uncircumcision.
