Ecclesiastes 11:1-12:14, Psalm 73:1-28, 88:1-18, 1 Kings 11:41-43, 2 Chronicles 9:29-31, 1 Kings 14:21, 2 Chronicles 12:13-14

11:5 5 As you do not know the path of the wind, or how the body is formed in a mother's womb, 

so you cannot understand the work of God, the Maker of all things.

Even as science discovers more and more - we still cannot understand the work of God.  The path of the wind is not 100% predictable.  How a body is formed in the womb is more understood, but there are still many, many unknowns that plague science about the miracle of life. 

 

I heard a joke once about some scientists who finally figured out how to create a person and went to show God that they were just as powerful as he was.  They knelt down to create a man from dirt when God interceded and told them to create their own dirt first.  The more we understand - the less we know.

12:13-14 ... Fear God and keep his commandments, 

for this is the whole [duty] of man. 
For God will bring every deed into judgment, 

including every hidden thing, whether it is good or evil. 

The psalms are cries to God.  Solomon was not a happy man the last years of his life.  When he died, his son Rehoboam, was king in Jerusalem.  Rehoboam did not seek God and 'did evil.'  He only reigned for 17 years.
