11 Again I saw that under the sun the race is not to the swift, nor the battle to the strong, nor bread to the wise, nor riches to the intelligent, nor favor to the skillful; but time and chance happen to them all. 12 For no one can anticipate the time of disaster. Like fish taken in a cruel net, and like birds caught in a snare, so mortals are snared at a time of calamity, when it suddenly falls 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.
