Ecclesiastes 3:11-13

11He has made everything beautiful in its time. He has also set eternity in the human heart; yet Or also placed ignorance in the human heart, so that no one can fathom what God has done from beginning to end. 12I know that there is nothing better for people than to be happy and to do good while they live. 13That each of them may eat and drink, and find satisfaction in all their toil—this is the gift of God.
