Ecclesiastes 3:10-12 (New International Version)

¹⁰ I have seen the burden God has laid on men. ¹¹ He has made everything beautiful in its time. He has also set eternity in the hearts of men; yet they cannot fathom what God has done from beginning to end. ¹² I know that there is nothing better for men than to be happy and do good while they live.
