91 All this I laid to heart, examining it all, how the righteous and the wise and their deeds are in the hand of God; whether it is love or hate one does not know. Everything that confronts them 2 is vanity, since the same fate comes to all, to the righteous and the wicked, to the good and the evil, to the clean and the unclean, to those who sacrifice and those who do not sacrifice. As are the good, so are the sinners; those who swear are like those who shun an oath. 3 This is an evil in all that happens under the sun, that the same fate comes to everyone. Moreover, the hearts of all are full of evil; madness is in their hearts while they live, and after that they go to the dead.

Commentary on Ecclesiastes 9:1-3

(Read Ecclesiastes 9:1-3)

We are not to think our searching into the word or works of God useless, because we cannot explain all difficulties. We may learn many things good for ourselves and useful to others. But man cannot always decide who are objects of God's special love, or under his wrath; and God will certainly put a difference between the precious and the vile, in the other world. The difference as to present happiness, arises from the inward supports and consolations the righteous enjoy, and the benefit they derive from varied trials and mercies. As far as the sons of men are left to themselves, their hearts are full of evil; and prosperity in sin, causes them even to set God at defiance by daring wickedness. Though, on this side death, the righteous and the wicked may often seem to fare alike, on the other side there will be a vast difference between them.
