14 There is a vanity which is done upon the earth; that there are righteous [men] unto whom it happeneth according to the work of the wicked; and there are wicked [men] to whom it happeneth according to the work of the righteous. I said that this also is vanity. 15 And I commended mirth, because there is nothing better for man under the sun than to eat, and to drink, and to be merry; for that shall abide with him of his labour the days of his life, which God hath given him under the sun. 16 When I applied my heart to know wisdom, and to see the business that is done upon the earth (for also there is that neither day nor night seeth sleep with his eyes), 17 then I saw that all [is] the work of God, [and] that man cannot find out the work that is done under the sun: because however man may labour to seek [it] out, yet doth he not find [it]; and even, if a wise [man] think to know [it], he shall not be able to find [it] out.
Matthew Henry's Commentary on Ecclesiastes 8:14-17
Commentary on Ecclesiastes 8:14-17
(Read Ecclesiastes 8:14-17)
Faith alone can establish the heart in this mixed scene, where the righteous often suffer, and the wicked prosper. Solomon commended joy, and holy security of mind, arising from confidence in God, because a man has no better thing under the sun, though a good man has much better things above the sun, than soberly and thankfully to use the things of this life according to his rank. He would not have us try to give a reason for what God does. But, leaving the Lord to clear up all difficulties in his own time, we may cheerfully enjoy the comforts, and bear up under the trials of life; while peace of conscience and joy in the Holy Ghost will abide in us through all outward changes, and when flesh and heart shall fail.
