But after thy hardness and impenitent heart treasurest up unto thyself wrath in the day of wrath and revelation of the righteous judgment of God. The "day of wrath" is the day of judgment, the final display of eternal righteousness, when the "forbearance" will be over; ever represented, notwithstanding the world's redemption, under a terrible aspect for the persistently impenitent (cf.
2 Thessalonians 1:9). It may be here observed again that it is ὁ κρίνων against whom these indignant denunciations are hurled, and this on the very ground of his thus setting himself up to judge while being himself guilty.
Of him it is implied, not only that he shares the guilt of mankind, but also that he especially will not escape the final judgment. Of others who, conscious of their own failings, seek sincerely alter good, this is not said, however liable to condemnation on their own mere merits they may be.
Indeed, the contrary is emphatically asserted in the verses that follow; nay, even eternal life is assured to such, whoever they may be, and under whatever dispensation, though it does not fall within the scope of the argument to explain in this place why or how.
It is important for us to see this clearly for an understanding of the drift of the chapter, and of St. Paul's whole doctrine with respect to human sin and its consequences.
