Ecclesiastes 3:9-13 New Revised Standard Version (NRSV)
The God-Given Task
9 What gain have the workers from their toil? 10 I have seen the business that God has given to everyone to be busy with. 11 He has made everything suitable for its time; moreover he has put a sense of past and future into their minds, yet they cannot find out what God has done from the beginning to the end. 12 I know that there is nothing better for them than to be happy and enjoy themselves as long as they live; 13 moreover, it is God’s gift that all should eat and drink and take pleasure in all their toil.
