The reason I'm asking is mainly that I'm considering doing this song for a church service, and I'm wondering if the religious reference is too subtle and/or ambiguous for it to be accepted.
(It's that subtlety in part that I really like about the lyrics to this song. I also love the music to it.)
I guess if "Christian recording artists" consider it to be at least spiritually relevant, maybe that should be enough. But I'd like to know how other people, especially folkies, interpret the lyrics too.

(And thanks, Maeve, for the contact link.)
