Romans

²⁴For the name of God is blasphemed among the Gentiles through you, as it is written. ²⁵For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision. ²⁶Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? ²⁷And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law? ²⁸For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: ²⁹But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
