Music and singing are necessary to Christian faith and worship for the simple reason that the realities of God and Christ, creation and salvation, heaven and hell are so great that when they are known truly and felt duly, they demand more than discussion and analysis and description; they demand poetry and song and music. Singing is the Christian's way of saying: God is so great that thinking will not suffice, there must be deep feeling; and talking will not suffice, there must be singing.
