This quote comes from Music Through the Eyes of Faith, by Harold Best. It’s the most biblical treatment of using music for the glory of God that I’ve read.
The Scriptures include or allude to just about every approach to worship there is: organized, spontaneous, public, private, simple, complex, ornate, or plain. Yet there is no comment anywhere about any one way being preferred over another. Rather, it is the spiritual condition of the worshiper that determines whether or not God is at work. This fact alone countermands the tendency to assume that if we could just find the correct or fashionably relevant system, all will be well and God will come down. This doesn’t imply that we have no responsibility to make intelligent and sensitive choices or to be creative. But whatever these choices eventually are, they are incapable all by themselves of establishing the superiority of one system over another. (p. 146)
