Römer 2:4

Or despisest thou the riches of his goodness - Wilt thou render of none effect that marked benevolence of God towards thee which has given so many superior advantages, and that forbearance which has tolerated thy many miscarriages, and that long-suffering which, after repeated provocations, still continues to bear with thee? Not knowing - Αγνοων, not acknowledging that this goodness of God, which has so long manifested itself in forbearance and long-suffering, leadeth thee to repentance - was designed to accomplish this blessed end; which thy want of consideration and acknowledgment has rendered, hitherto, ineffectual. This was a maxim among the Jews themselves; for, in Synopsis Sohar, it is said: - The holy blessed God delays his anger against the wicked, to the end that they may repent and be converted.

THE JEW UNDER LIKE CONDEMNATION WITH THE GENTILE. (Rom. 2:1-29) the goodness of God leadeth thee to repentance--that is, is designed and adapted to do so.

Or despisest thou the riches of his goodness,.... The apostle anticipates an objection against what he had said, taken from the prosperity of these persons; who might conclude from thence, that they were not so wicked as he had represented them; and that they should escape the judgment of God, otherwise they would have been punished by God in this life, and not have prospered as they did; which objection is removed by observing, that it was not their innocence, but "the riches of" divine "goodness, and longsuffering and forbearance", which were the causes of their prosperity: by "the riches of God's goodness", are not meant the riches of his special, spiritual, and eternal goodness, which his own people are only partakers of: but the general riches of his temporal and providential goodness, which the men of the world have commonly the greatest share of; they have it in great plenty, which is signified by "riches": and by his "longsuffering and forbearance" are designed, not his forbearance of his chosen ones and his longsuffering to them, which issue in their salvation; but his forbearance of sinners, and longsuffering towards them, in not as yet pouring down his wrath and displeasure on them; all which are "despised" by them; the riches of his goodness, when he is not glorified for his providential mercies, and in them, and when these are abused to the lusts of men. The forbearance of God is despised, when men on account of it harden themselves in sin; and his longsuffering, when they deny his concern in Providence, or a future judgment, and promise themselves impunity. Moreover, the apostle obviates the above objection by asserting that God's end in his goodness, forbearance, and longsuffering, was not to testify to their innocence, as they imagined, but to lead them…

The scope of the first two chapters of this epistle may be gathered from Rom 3:9, "We have before proved both Jews and Gentiles that they are all under sin." This we have proved upon the Gentiles (ch. 1), now in this chapter he proves it upon the Jews, as appears by Rom 2:17, "thou art called a Jew." I. He proves in general that Jews and Gentiles stand upon the same level before the justice of God, to Rom 2:11. II. He shows more particularly what sins the Jews were guilty of, notwithstanding their profession and vain pretensions (Rom 2:17 to the end).

2:4 Can’t you see that his kindness is intended to turn you from your sin? Behind Paul’s question are Jewish passages (e.g., Wisdom of Solomon 12–15; cp. Jer 7:1-5; Amos 5:18-27) that portray a prevalent Jewish complacency toward judgment. Many Jews thought that because they were God’s people, they did not need to worry about judgment, for their sins would not be punished as the sins of Gentiles would be. Paul emphasizes that God’s grace was intended to turn the Jews from their sin, not to condone a sinful lifestyle.
