14 There is a vanity that takes place on earth, that there are righteous people to whom it happens according to the deeds of the wicked, and there are wicked people to whom it happens according to the deeds of the righteous. I said that this also is vanity. 15 And I commend joy, for man has no good thing under the sun but to eat and drink and be joyful, for this will go with him in his toil through the days of his life that God has given him under the sun. 16 When I applied my heart to know wisdom, and to see the business that is done on earth, how neither day nor night do one's eyes see sleep, 17 then I saw all the work of God, that man cannot find out the work that is done under the sun. However much man may toil in seeking, he will not find it out. Even though a wise man claims to know, he cannot find it out.

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.
