Ecclesiastes 8:16-17 - No One Can Discover The Rhyme And Reason For Things
16 When I applied my 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), 17 then I beheld all the work of God, that man cannot find out the work that is done under the sun: because however much a man labor to seek it out, yet he shall not find it; yea moreover, though a wise man think to know it, yet shall he not be able to find it.
