Ecclesiastes 3:9-13 NIV

[9] What do workers gain from their toil? [10] I have seen the burden God has laid on the human race. [11] He has made everything beautiful in its time. He has also set eternity in the human heart; yet no one can fathom what God has done from beginning to end. [12] I know that there is nothing better for people than to be happy and to do good while they live. [13] That each of them may eat and drink, and find satisfaction in all their toil—this is the gift of God.
