Ecclesiastes 8:14 says, There is a vanity which is done upon the earth; that there be just men, unto whom it happeneth according to the work of the wicked; again, there be wicked men, to whom it happeneth according to the work of the righteous: I said that this also is vanity.  I believe that Solomon was exploring the question we hear so often today, which is why do the evil prosper while the righteous suffer.  Solomon is saying that even if that is the case, we can never blame God.  Again, my understanding of this idea would be that we cannot claim that everything that happens in life is caused by God or is His will.  If it is, then we could indeed hold God accountable.  I realize that some people hold a different view, and that they see God as controlling ever aspect of life but as I have stated many times, this is not my understanding.  When bad things happen to good people, that is not God's will, but the result of people being given the freedom of choice.  Verse fifteen says,  Then I commended mirth, because a man hath no better thing 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 giveth him under the sun.  Solomon said he commended mirth, or joy.  We, as God's people, should indeed be full of joy, no matter what is going on in the world.  We can really ask for nothing more than to eat, sleep and be merry, or joyful. A lot of money is spent today just to help people sleep, often because they are just too worried about gaining and maintaining the things of this world.   Verse sixteen and seventeen say, When I applied mine 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:) Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man labour to seek it out, yet he shall not find it; yea further; though a wise man think to know it, yet shall he not be able to find it.   I believe Solomon is saying that even if we spend every moment day and night attempting understand everything that happens in the world, we would never be successful.  All we would accomplish is losing sleep and giving in to worry.  We must acknowledge that there are some things that we can never understand.  Like Adam and Eve, we may want to be as knowledgeable as God, but we never will be.  We must, as followers of Christ, learn to be content with simply enjoying our lives in a right relationship with Him.  As long as we accept that we have everlasting life with God, not someday but from the day we accept Christ as our Savior, then nothing else of this world really matters.
