Ecclesiastes 3:11-14; Ecclesiastes 3:22

11 He hath made everything beautiful in its time: also he hath set eternity in their heart, yet so that man cannot find out the work that God hath 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 so long as they live.

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

14 I know that, whatsoever God doeth, it shall be for ever: nothing can be put to it, nor anything taken from it; and God hath done it, that men should fear before him.

22 Wherefore I saw that there is nothing better, than that a man should rejoice in his works; for that is his portion: for who shall bring him [back] to see what shall be after him?
