Ecclesiastes 3:9-15

9What profit has the worker from that in which he labors?

10I have seen the God-given task with which the sons of men are to be occupied.

11He has made everything beautiful in its time. Also He has put eternity in their hearts, except that no one can find out the work that God does from beginning to end.

12I know that nothing is better for them than to rejoice, and to do good in their lives,

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

14I know that whatever God does, It shall be forever. Nothing can be added to it, And nothing taken from it. God does it, that men should fear before Him.

15That which is has already been, And what is to be has already been; And God requires an account of what is past.
