God is a person, and his universe reflects his personhood. The closer something is to the character of God, the more it reflects him and the less it can be measured. Things such as integrity, beauty, hope, and love are all in the same category as prayer. You can tell their presence and even describe them, but you can't define them, simply because they are too close to God's image.
