I'm not terribly religious, but I was struck by this quote. Mentally edit to match the divine spirit of your choice. From the movie "Copying Beethoven" (which, by the way, is both moving and funny in all the right places - I highly recommend it):
"The vibrations on the air are the breath of God speaking to man's soul. Music is the language of God. We musicians are as close to God as man can be. We hear his voice, we read his lips, we give birth to the children of God, who sing his praise. That's what musicians are."
