I haven't been doing much Xmas music posting this year, sorry. But here's one I haven't heard in years. Not exactly a standard in the pop-music cycles.
Seems strange that when I hear it, I think it should be sung loudly and with joyous voices. Seems strange for someone who left the church long ago, but I think it's because this song speaks to the part of Christianity I love. Not the "Onward Christian Soldiers" drumbeat, but the quiet grace and joy of the message.
