The Importance of Sharing in the Divine Nature

In the Old Testament, Hebrew kings and holy man could be called God's sons. But they weren't literally thought to be God in the way that the New Testament thinks that Jesus is fully divine. So I wouldn't take, as you say, that passage to mean God with the capital G. We're clearly creatures who don't share in the divine nature; otherwise we would have two natures,. As he does his sanctifying work in him, we will become more Christ-like in our character but we'll never become necessary, self-existent, omnipotent beings.
