Ecclesiastes 3:10-12

¹⁰I have seen the burden which God has given to the sons of men to be afflicted with.

¹¹He has made everything beautiful in its time. He has also set eternity in their hearts, yet so that man can’t find out the work that God has done from the beginning even to the end.

¹²I know that there is nothing better for them than to rejoice, and to do good as long as they live.
