17 You who call yourselves Jews are relying on God's law, and you boast about your special relationship with him. 18 You know what he wants; you know what is right because you have been taught his law. 19 You are convinced that you are a guide for the blind and a light for people who are lost in darkness. 20 You think you can instruct the ignorant and teach children the ways of God. For you are certain that God's law gives you complete knowledge and truth. 21 Well then, if you teach others, why don't you teach yourself? You tell others not to steal, but do you steal? 22 You say it is wrong to commit adultery, but do you commit adultery? You condemn idolatry, but do you use items stolen from pagan temples? 23 You are so proud of knowing the law, but you dishonor God by breaking it. 24 No wonder the Scriptures say, "The Gentiles blaspheme the name of God because of you." 25 The Jewish ceremony of circumcision has value only if you obey God's law. But if you don't obey God's law, you are no better off than an uncircumcised Gentile. 26 And if the Gentiles obey God's law, won't God declare them to be his own people? 27 In fact, uncircumcised Gentiles who keep God's law will condemn you Jews who are circumcised and possess God's law but don't obey it. 28 For you are not a true Jew just because you were born of Jewish parents or because you have gone through the ceremony of circumcision. 29 No, a true Jew is one whose heart is right with God. And true circumcision is not merely obeying the letter of the law; rather, it is a change of heart produced by the Spirit. And a person with a changed heart seeks praise from God, not from people.

Commentary on Romans 2:17-24
(Read Romans 2:17-24)
The apostle directs his discourse to the Jews, and shows of what sins they were guilty, notwithstanding their profession and vain pretensions. A believing, humble, thankful glorying in God, is the root and sum of all religion. But proud, vain-glorious boasting in God, and in the outward profession of his name, is the root and sum of all hypocrisy. Spiritual pride is the most dangerous of all kinds of pride. A great evil of the sins professors is, the dishonour done to God and religion, by their not living according to their profession. Many despise their more ignorant neighbours who rest in a dead form of godliness; yet themselves trust in a form of knowledge, equally void of life and power, while some glory in the gospel, whose unholy lives dishonour God, and cause his name to be blasphemed.
Commentary on Romans 2:25-29
(Read Romans 2:25-29)
No forms, ordinances, or notions can profit, without regenerating grace, which will always lead to seeking an interest in the righteousness of God by faith. For he is no more a Christian now, than he was really a Jew of old, who is only one outwardly: neither is that baptism, which is outward in the flesh: but he is the real Christian, who is inwardly a true believer, with an obedient faith. And the true baptism is that of the heart, by the washing of regeneration and the renewal of the Holy Ghost; bringing a spiritual frame of mind, and a willing following of truth in its holy ways. Let us pray that we may be made real Christians, not outwardly, but inwardly; in the heart and spirit, not in the letter; baptized, not with water only, but with the Holy Ghost; and let our praise be, not of men, but of God.
