Music, of course, does not remake us; the Holy Spirit does. But it seems possible that music may be one means by which the Holy Spirit makes us people who feel and respond. We are brought to our senses. We are drawn out of the darkness of self-absorption and become aware of the world around us, our place within and responsibility to it.
In song we move in a dance of sympathy with the others who are singing, and by the body are drawn out of ourselves and into the Body.
