I won't even get into the question of what qualifies as spiritual, or to whom - I think I understand what you're asking for. Bob Franke's music would be a great source - particularly "The Great Storm Is Over" or "Thanksgiving Eve."

David Dodson has written a wonderful song called "The Farthest Field," which I think Bok, Trickett and Muir recorded on their last album together, "Harbors of Home." I doubt sheet music is available.

Good luck!
