We must beware of the naïve idea that our music can ‘please’ God as it would please a cultivated human hearer. That is like thinking, under the old Law, that He really needed the blood of bulls and goats. To which an answer came, mine are the cattle upon a thousand hills,’ and ‘if I am hungry, I will not tell thee.’ If God (in that sense) wanted music, He would not tell us. For all our offerings, whether of music or martyrdom, are like the intrinsically worthless present of a child, which a father values indeed, but values only for the intention.
—C.S. Lewis, “On Church Music” in Christian Reflections, 98-99
