This is David Haas’s setting of Mary Louise Bringle‘s enchanting text.
I only discovered who wrote the words when I found a sample page on the GIA site that was very well hidden. I had made up some simplified chords for the tune before I saw the real music and while I guessed a fair few of them my arrangements is pretty basic compared to Haas’s sophistication.
You can purchase this in a collection called God Never Tires at GIA. You can listen to the whole song there as well. To see the text scroll down to Hymn Tunes of David Haas – Volume Two and open the preview to page 6.
