91 But 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, man does not know; both are before him. 2 It is the same for all, since the same event happens to the righteous and the wicked, to the good and the evil,[1] to the clean and the unclean, to him who sacrifices and him who does not sacrifice. As the good one is, so is the sinner, and he who swears is as he who shuns an oath. 3 This is an evil in all that is done under the sun, that the same event happens to all. Also, the hearts of the children of man are full of evil, and madness is in their hearts while they live, and after that they go to the dead.
Matthew Henry's Commentary on Ecclesiastes 9:1-3
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.
