But instead of recognizing that God’s goodness and patience towards them was designed to give them space to repent, the apostle observes that many of them simply take advantage of divine forbearance to harden themselves in their sins, and make themselves more and more odious to Heaven’s justice.  By hardening their hearts and refusing to repent, the Jew placed himself in the dreadful position of “treasuring up wrath against the day of wrath and revelation of the righteous judgment of God.”

Such wickedness represented the most extreme folly to be found among the sons of men.  The Jew, being so well acquainted with the scriptures, and with his own history, knew that the wrath of God was a tremendous reality, and was surely not something to be trifled with.  Nevertheless, he flattered himself in his own security as a son of Abraham, and thought that he would never suffer the same destruction as must befall the heathen Gentiles.  The apostle attempts to dissuade them from this path of reckless abandon, by reminding them of the doctrine of their own scriptures, that God will render to every man according to his deeds.  This word of Psalm 62:12 held as true for the Jew as for the Gentile.
