Romans 2:22-26

Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?

Thou that makest thy boast of the law, through breaking the law dishonourest thou God?

For the name of God is blasphemed among the Gentiles through you, as it is written.

For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.

Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
