In administering human society God so tempers his providence that, although kindly and beneficent toward all in numberless ways, he still by open and daily indications declares his clemency to the godly and his severity to the wicked and criminal. For there are no doubts about what sort of vengeance he takes on wicked deeds. Thus he clearly shows himself the protector and vindicator of innocence, while he prospers the life of good men with his blessing, relieves their need, soothes and mitigates their pain, and alleviates their calamities; and in all these things he provides for their salvation. And indeed the unfailing rule of his righteousness ought not to be obscured by the fact that he frequently allows the wicked and malefactors to exult unpunished for some time, while he permits the upright and deserving to be tossed about by many adversities, and even to be oppressed by the malice and iniquity of the impious. But a far different consideration ought, rather, to enter our minds: that, when with a manifest show of his anger he punishes one sin, he hates all sins; that, when he leaves many sins unpunished, there will be another judgment to which have been deferred the sins yet to be punished. Similarly, what great occasion he gives us to contemplate his mercy when he often pursues miserable sinners with unwearied kindness, until he shatters their wickedness by imparting benefits and by recalling them to him with more than fatherly kindness!
