Ecclesiastes 8:7; Ecclesiastes 8:15; Ecclesiastes 8:17
Indeed, how can people avoid what they don't know is going to happen?
So I recommend having fun, because there is nothing better for people to do in this world than to eat, drink, and enjoy life. That way they will experience some happiness along with all the hard work God gives them.
This reminded me that no one can discover everything God has created in our world, no matter how hard they work at it. Not even the wisest people know everything, even if they say they do.
