3:22 Wherefore I perceive that [there is] nothing better, than that a man should {l} rejoice in his own works; for that [is] his portion: for who shall bring him to see what shall be after him?
(l) By the often repetition of this sentence as in Ec 2:24,3:12,22,5:17,8:15 he declares that man by reason can comprehend nothing better in this life than to use the gifts of God soberly and comfortably: for to know further, is a special gift of God revealed by his Spirit.
3:22 Better - For a man's present satisfaction. Should rejoice - That he comfortably enjoys what God hath given him. His portion - This is the benefit of his labours. For - When once he is dead he shall never return to see into whose hands his estate falls.
3:16-22 Without the fear of the Lord, man is but vanity; set that aside, and judges will not use their power well. And there is another Judge that stands before the door. With God there is a time for the redressing of grievances, though as yet we see it not. Solomon seems to express his wish that men might perceive, that by choosing this world as their portion, they brought themselves to a level with the beasts, without being free, as they are, from present vexations and a future account. Both return to the dust from whence they were taken. What little reason have we to be proud of our bodies, or bodily accomplishments! But as none can fully comprehend, so few consider properly, the difference between the rational soul of man, and the spirit or life of the beast. The spirit of man goes upward, to be judged, and is then fixed in an unchangeable state of happiness or misery. It is as certain that the spirit of the beast goes downward to the earth; it perishes at death. Surely their case is lamentable, the height of whose hopes and wishes is, that they may die like beasts. Let our inquiry be, how an eternity of existence may be to us an eternity of enjoyment? To answer this, is the grand design of revelation. Jesus is revealed as the Son of God, and the Hope of sinners.
