Ecclesiastes 3:11-13

11He 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.

12I perceived that there is nothing better for them than to be joyful and to do good as long as they live;

13also that everyone should eat and drink and take pleasure in all his toil—this is God's gift to man.
