17 But if you call yourself a Jew and rely on the law and boast of your relation to God 18 and know his will and determine what is best because you are instructed in the law, 19 and if you are sure that you are a guide to the blind, a light to those who are in darkness, 20 a corrector of the foolish, a teacher of children, having in the law the embodiment of knowledge and truth, 21 you, then, that teach others, will you not teach yourself? While you preach against stealing, do you steal? 22 You that forbid adultery, do you commit adultery? You that abhor idols, do you rob temples? 23 You that boast in the law, do you dishonor God by breaking the law?
Matthew Henry's Commentary on Romans 2:17-23
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.
