Romans 2:19-25

2:19 and if you are convinced that you yourself are a guide to the blind, a light to those who are in darkness, 2:20 an educator of the senseless, a teacher of little children, because you have in the law the essential features of knowledge and of the truth – 2:21 therefore you who teach someone else, do you not teach yourself? You who preach against stealing, do you steal? 2:22 You who tell others not to commit adultery, do you commit adultery? You who abhor idols, do you rob temples? 2:23 You who boast in the law dishonor God by transgressing the law! 2:24 For just as it is written, “the name of God is being blasphemed among the Gentiles because of you.”

2:25 For circumcision has its value if you practice the law, but if you break the law, your circumcision has become uncircumcision.
