Ecclesiastes 3:11-14; Ecclesiastes 3:22
He has made everything beautiful in its time. Also, he has put eternity into man's heart, yet so that he cannot find out what God has done from the beginning to the end.
I perceived that there is nothing better for them than to be joyful and to do good as long as they live;
also that everyone should eat and drink and take pleasure in all his toil--this is God's gift to man.
I perceived that whatever God does endures forever; nothing can be added to it, nor anything taken from it. God has done it, so that people fear before him.
So I saw that there is nothing better than that a man should rejoice in his work, for that is his lot. Who can bring him to see what will be after him?
