God became man, not so that he might be with us, but so that we might be with him. In other words, the incarnation is the starting point of our divinization.…It comes about so that, having become in a sense ‘divine,’ we may be capable of effectively working with Christ to rebuild the world for the glory of the father. We are thus not passive bystanders at the incarnation. The incarnation radically transforms the history of the world and the personal history of each of us.
