God creates for a reason

Tollkien saw natural things freighted with the depth of meaning that all things possess, being rooted in the mind of God. God does not create things simply to fill up space. God creates for a reason, and the ultimate reason for his creation is love. Each thing, and especially each living thing, is a word, a symbol, a revelation. Each is a note, or a theme, in some great music. At any rate, it is more than itself: that is, more than the thing most people see when they look at it.
