8:14. There is also another vanity, which is done upon the earth. There are just men to whom evils happen, as though they had done the works of the wicked: and there are wicked men, who are as secure as though they had the deeds of the just: but this also I judge most vain.
8:15. Therefore I commended mirth, because there was no good for a man under the sun, but to eat, and drink, and be merry, and that he should take nothing else with him of his labour in the days of his life, which God hath given him under the sun.
No good for a man, etc… Some commentators think the wise man here speaks in the person of the libertine: representing the objections of these men against divine providence, and the inferences they draw from thence, which he takes care afterwards to refute. But it may also be said, that his meaning is to commend the moderate use of the goods of this world, preferably to the cares and solicitudes of worldlings, their attachment to vanity and curiosity, and presumptuously diving into the unsearchable ways of divine providence.
8:16. And I applied my heart to know wisdom, and to understand the distraction that is upon earth: for there are some that day and night take no sleep with their eyes.
8:17. And I understood that man can find no reason of all those works of God that are done under the sun: and the more he shall labour to seek, so much the less shall he find: yea, though the wise man shall say, that he knoweth it, he shall not be able to find it.
Ecclesiastes Chapter 9
Man knows not certainty that he is in God's grace. After death no more work or merit.
9:1. All these things have I considered in my heart, that I might carefully understand them: there are just men and wise men, and their works are in the hand of God: and yet man knoweth not whether he be worthy of love, or hatred:
9:2. But all things are kept uncertain for the time to come, because all things equally happen to the just and to the wicked, to the good and to the evil, to the clean and to the unclean, to him that offereth victims, and to him that despiseth sacrifices. As the good is, so also is the sinner: as the perjured, so he also that sweareth truth.
9:3. This is a very great evil among all things that are done under the sun, that the same things happen to all men: whereby also the hearts of the children of men are filled with evil, and with contempt while they live, and afterwards they shall be brought down to hell.
