John Chrysostom

"Or despiseth thou the riches of His goodness and forbearance and long-suffering; not knowing that the goodness of God leadeth thee to repentance?" For after praising God's long-suffering, showing the gain thereof to be very great to them that heeded it (and this was the drawing sinners to repentance); he adds to the terror. For as to them, who avail themselves of it aright, it is a ground of safety; so to them that slight it, it is conducive to a greater vengeance. For whenever you utter this common notion, that God doth not exact justice, because He is good and long-suffering, he says, You do but mention what will make the vengeance intenser. For God showeth His goodness that you may get free from your sins, not that you may add to them. If then thou make not this use thereof, the judgment will be more fearful. Wherefore it is a chief ground for abstaining from sin, that God is long-suffering, and not for making the benefit a plea for obstinacy. For if He be long-suffering, He most certainly punisheth. Whence does this appear? from what is next said. For if the wickedness be great and the wicked have not been requited, it is absolutely necessary that they should be requited. For if men do not overlook these things, how should God make an oversight? And so from this point he introduces the subject of the judgment. For the fact of showing many who, if they repent not, are liable, yet still are not punished here, introduces with it necessarily the judgment, and that with increase.
