Ecclesiastes 3:11-14; Ecclesiastes 3:22

11 He has made everything beautiful in its time. He has also set eternity in their hearts, yet so that man can't find out the work that God has done from the beginning even to the end.

12 I know that there is nothing better for them than to rejoice, and to do good as long as they live.

13 Also that every man should eat and drink, and enjoy good in all his labor, is the gift of God.

14 I know that whatever God does, it shall be forever. Nothing can be added to it, nor anything taken from it; and God has done it, that men should fear before him.

22 Therefore I saw that there is nothing better, than that a man should rejoice in his works; for that is his portion: for who can bring him to see what will be after him?
