2 The whole 'is' as to the whole; one event is to the righteous and to the wicked, to the good, and to the clean, and to the unclean, and to him who is sacrificing, and to him who is not sacrificing; as 'is' the good, so 'is' the sinner, he who is swearing as he who is fearing an oath. 3 This 'is' an evil among all that hath been done under the sun, that one event 'is' to all, and also the heart of the sons of man is full of evil, and madness 'is' in their heart during their life, and after it—unto the dead.
Matthew Henry's Commentary on Ecclesiastes 9:2-3
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.
