Ecclesiastes 8:16-17 - No One Can Discover The Rhyme And Reason For Things
16 When I tried to gain wisdom and to observe the activity on earth -- even though it prevents anyone from sleeping day or night -- 17 then I discerned all that God has done: No one really comprehends what happens on earth. Despite all human efforts to discover it, no one can ever grasp it. Even if a wise person claimed that he understood, he would not really comprehend it.
