Romans 2:17-29

Indeed you are called a Jew, and rest in the law, and make your boast in God. You know His will and approve the things that are more excellent, because you are instructed in the law. You are confident that you are a guide to the blind, a light to those who are in darkness, an instructor of the foolish, and a teacher of babes, who have the full content of knowledge and truth in the law: You, therefore, who teach another, do you not teach yourself? You who preach not to steal, do you steal? You who say not to commit adultery, do you commit adultery? You who abhor idols, do you rob temples? You who boast in the law, do you dishonor God through breaking the law? As it is written, “The name of God is blasphemed among the Gentiles because of you.” Circumcision indeed has merit, if you keep the law, but if you are a breaker of the law, your circumcision becomes uncircumcision. Therefore, if an uncircumcised man keeps the righteousness of the law, will not his uncircumcision be counted as circumcision? Will the uncircumcised one who is righteous by nature, if he fulfills the law, not judge you who, by the letter of the law and circumcision, violate the law? He is not a Jew who is one outwardly, nor is circumcision that which is external in the flesh. But he is a Jew who is one inwardly. And circumcision is of the heart, by the Spirit, and not by the letter. His praise is not from men, but from God.
