We are called upon to “glorify God” -- what does that mean?

The glorification of God does not consist in merely saying that God is great. That is only verbal and there is no virtue in it. To glorify God means that the reality deposited within the human temple, the reality which is the image and likeness of God, shall become revealed through man. That reality consists in the virtues and perfections of the human world. It consists in the knowledge of all truth. When such lights become manifest from him, then he has indeed glorified God. Otherwise, the glorification of God is only a verbal ceremony.
