Ecclesiastes 3:9-13

9 What gain has the worker from his toil? 10 I have seen the business that God has given to the children of man to be busy with. 11 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. 12 I perceived that there is nothing better for them than to be joyful and to do good as long as they live; 13 also that everyone should eat and drink and take pleasure in all his toil—this is God’s gift to man.
