91 For all this I laid to my heart, even to explore all this: that the righteous, and the wise, and their works, are in the hand of God; whether it is love or hatred, man doesn’t know it; all is before them. 2 All things come alike to all. There is one event to the righteous and to the wicked; to the good, to the clean, to the unclean, to him who sacrifices, and to him who doesn’t sacrifice. As is the good, so is the sinner; he who takes an oath, as he who fears an oath. 3 This is an evil in all that is done under the sun, that there is one event to all: yes also, the heart of the sons of men is full of evil, and madness is in their heart 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.
