The silence of the marsh was so profound that it could have been the flip side of the singing in my church. Just last Sunday the people had sung the old spiritual, "Go Down, Moses," a cappella because the pianist was gone, and a bunch of people were crying, singing very loudly with their eyes closed, and the singing of that cry of a song was a wonderful form of communion. How come you can hear a chord, and then another chord, and then your heart breaks open?
