Through theoria, the knowledge of God in Jesus Christ, human beings come to know and experience what it means to be fully human (the created image of God); through their communion with Jesus Christ God shares Himself with the human race, in order to conform them to all that God is in knowledge, righteousness and holiness. Theosis also asserts the complete restoration of all people (and of the entire creation), in principle. This is built upon the understanding of the atonement put forward by Irenaeus of Lyons, called "recapitulation."For the Orthodox, you are going to hear a lot about the importance of the Incarnation in salvation-- the idea that God becoming human associates creation with God and divinity in a way that it didn't before. So while the evangelicals might concentrate primarily on the legal ramifications of sacrificing Christ to ensure forgiveness on God's legal ledger, the Orthodox are going to concentrate on the paradox of God experiencing and participating in death and how that saves humanity.
For many fathers, theosis goes beyond simply restoring people to their state before the Fall of Adam and Eve, teaching that because Christ united the human and divine natures in his person, it is now possible for someone to experience closer fellowship with God than Adam and Eve initially experienced in the Garden of Eden, and that people can become more like God than Adam and Eve were at that time. Some Orthodox theologians go so far as to say that Jesus would have become incarnate for this reason alone, even if Adam and Eve had never sinned.
