And I know that whatever God does is final. Nothing can be added to it or taken from it. God's purpose in this is that people should fear him.
Whatever exists today and whatever will exist in the future has already existed in the past. For God calls each event back in its turn.
References for Ecclesiastes 3:15
I also noticed that throughout the world there is evil in the courtroom. Yes, even the courts of law are corrupt!
I said to myself, "In due season God will judge everyone, both good and bad, for all their deeds."
Then I realized that God allows people to continue in their sinful ways so he can test them. That way, they can see for themselves that they are no better than animals.
For humans and animals both breathe the same air, and both die. So people have no real advantage over the animals. How meaningless!
References for Ecclesiastes 3:19
Both go to the same place -- the dust from which they came and to which they must return.
For who can prove that the human spirit goes upward and the spirit of animals goes downward into the earth?
So I saw that there is nothing better for people than to be happy in their work. That is why they are here! No one will bring them back from death to enjoy life in the future.
