On Michael Herry’s site he calls this a “Hymn of Trust”. The words and sheet music are there as well. He also has a version by the Marist Singers on this site.
His site says the text of the refrain is anonymous but adapted by Tricia Walsh. The verses are adapted from psalm 138.
CWB II says the verse is translated from a source of Pauline charism by Fr Walter Silvester and the verses are The Grail translation of the psalm. Make of all that as you will.
I prefer Herry’s sheet music although he pitches it in Eb and CWB II brings it down to D. He also has different markers for emphasis for the chant in the verses.
I made a backing to learn the refrain mainly. I did include the verses but used notes for the tones rather than each word because BIAB CAN”T DO CHANT.
