Romans 2:21-25

21you, then, who teach others, do you not teach yourself? You who preach against stealing, do you steal? 22You who say that people should not commit adultery, do you commit adultery? You who abhor idols, do you rob temples? 23You who boast in the law, do you dishonor God by breaking the law? 24As it is written: “God’s name is blasphemed among the Gentiles because of you.” 25Circumcision has value if you observe the law, but if you break the law, you have become as though you had not been circumcised.
