Kris Morrison teaches one of the Psalms of Ascents. It compares the “vain” or meaningless life that we can toil at without God, and compares it to the rich and meaningful life we can have with God.
A Song of Ascents. Of Solomon.
127 Unless the Lord builds the house,
those who build it labor in vain.
Unless the Lord watches over the city,
the watchman stays awake in vain.
2 It is in vain that you rise up early
and go late to rest,
eating the bread of anxious toil;
for he gives to his beloved sleep.
