Romans 2:17-29 (KJV) ¹⁷  Behold, thou art called a Jew, and restest in the law, and makest thy boast of God, ¹⁸  And knowest his will, and approvest the things that are more excellent, being instructed out of the law; ¹⁹  And art confident that thou thyself art a guide of the blind, a light of them which are in darkness, ²⁰  An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law. ²¹  Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal? ²²  Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege? ²³  Thou that makest thy boast of the law, through breaking the law dishonourest thou God? ²⁴  For the name of God is blasphemed among the Gentiles through you, as it is written. ²⁵  For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision. ²⁶  Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? ²⁷  And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law? ²⁸  For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: ²⁹  But 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.
