11 I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to the intelligent, nor yet favour to men of knowledge; but time and chance happeneth to them all. 12 For man also knoweth not his time: as the fishes that are taken in an evil net, and as the birds that are taken with the snare, like them are the children of men snared in an evil time, when it falleth suddenly upon them.
Matthew Henry's Commentary on Ecclesiastes 9:11-12
Commentary on Ecclesiastes 9:11-12
(Read Ecclesiastes 9:11-12)
Men's success seldom equals their expectations. We must use means, but not trust to them: if we succeed, we must give God the praise; if crossed, we must submit to his will. Those who put off the great concerns of their souls, are caught in Satan's net, which he baits with some worldly object, for which they reject or neglect the gospel, and go on in sin till they suddenly fall into destruction.
