To sum up: there are two sides of God that correspond to two states of the human being. In Aristotelian terms, there is a God in actuality, and a God in potentiality. From one point of view, God has never left his state of perfect repose in pure being. This is “He Who Stood,” or the Infinite Power. From another point of view, God is in a process of constant evolution. He starts in the human being as the Seventh Power, though in seed form. The Seventh Power eventually attains realization in human consciousness. These two sides of God—namely, the eternally completed as well as the maturing God—are ultimately one, such that one aspect of God can say to the other: “I and you are one. What is before me is you. What is after you is I.”
Importantly, since the Seventh Power attains its perfection in human consciousness, it is also the human who can say to God: “I and you are one. What is before me is you. What is after you is I.” The God in potentiality is inside every human being. When God attains actuality, the human being is deified. God is developing in the human, and in the course of divine evolution, human consciousness attains a divine level. In this scheme, deification means transcending this world of generation, becoming pure, unborn Spirit in all respects equal to the Infinite Power.
