12 For all who have sinned vwithout the law will also perish without the law, and all who have sinned under the law will be judged by the law. 13 For wit is not the hearers of the law who are righteous before God, but the doers of the law who will be justified. 14 For when Gentiles, who do not have the law, xby nature do what the law requires, they are a law to themselves, even though they do not have the law. 15 They show that the work of the law is ywritten on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them 16 zon that day when, aaccording to my gospel, God judges bthe secrets of men cby Christ Jesus.
17 But if you call yourself a Jew and drely on the law and boast in God 18 and know his will and approve what is excellent, because you are instructed from the law; 19 and if you are sure that you yourself are ea guide to the blind, a light to those who are in darkness, 20 an instructor of the foolish, a teacher of children, having in the law fthe embodiment of gknowledge and truth— 21 hyou then who teach others, do you not teach yourself? While you preach against stealing, do you steal? 22 You who say that one must not commit adultery, do you commit adultery? You who abhor idols, do you irob temples? 23 You who jboast in the law kdishonor God by breaking the law. 24 For, las it is written, “The name of God is blasphemed mamong the Gentiles because of you.”
25 For circumcision indeed is of value nif you obey the law, but if you break the law, your circumcision becomes uncircumcision. 26 So, if oa man who is uncircumcised keeps pthe precepts of the law, will not his uncircumcision be regarded2 as circumcision? 27 Then he who is physically3 uncircumcised but keeps the law qwill condemn you who have rthe written code4 and circumcision but break the law. 28 For sno one is a Jew twho is merely one outwardly, nor is circumcision outward and physical. 29 But a Jew is one uinwardly, and vcircumcision is a matter of the heart, by the Spirit, not by the letter. wHis praise is not from man but from God.
