Listen again to the new song from Nick Flynn. Words are by Ellen Carr. The song is based on two verses from the Bible, Philippians 4 v 6 and 7 which read:
6 Do not be anxious about anything,

by prayer and petition,
with thanksgiving, present your requests to God.
7 And the peace of God,
which transcends all understanding,
will guard your hearts and your minds in Christ Jesus.
Here is a version without commentary:
