Faith is a footbridge that you don't know will hold you up over the chasm until you're forced to walk out onto it.
Sometimes the reason offered for seeking aesthetic excellence in the music of the church is that thereby one pleases God. I think that is true. But not because we know what music God enjoys- though I suspect it must be music which is unified, rich, and intense! Rather, because it is in the joy of his people that God finds delight.
