I had originally planned to do 4 posts, one for each stanza. This post makes #13, and I have only gotten to lines 3 and 4 of the first stanza.
The series will pick up again sometime in the new year, possibly towards the end of Epiphany and the beginning of Lent. The hymn is the appointed Hymn of the Day for Lent 1.
For now, let's settle in for Advent.
