Brendan suggested this song as a bridge between Carols and the actual Christmas Mass, which sounds a nice idea as I’m not sure it’s really a liturgical song but has possibilities as a solo vehicle along with major risks of over-emoting.
It is by Mark Lowry and Buddy Greene and seems to be have covered by everyone, but I can’t recall hearing of it before.
The text is here and there are various arrangements for sale online. (eg musicnotes and sheetmusicplus)
I had fun making a backing, and you know Mary needs accordion:
I found pages of You-Tube clips of covers of this song, here’s just a few:

Los Cantantes Catolicos
Jordan Smith (The Voice 2015)
CeeLo Green
