“According to the teachings of the Holy Bible and the Fathers of the Church, man is able to achieve Theosis because within the Orthodox Church of Christ the Grace of God is uncreated. God is not only essence, as the West thinks; He is also energy. If God was only essence, we could not unite with Him, could not commune with Him, because the essence of God is awesome and unapproachable for man, as was written: “Never will man see My face and live” (Exodus 33:20). Let us give a relevant example from things human. If we grasp a bare electric wire, we will die. However, if we connect a lamp to the same wire, we are illuminated. We see, enjoy, and are assisted by, the energy of electric current, but we are not able to grasp its essence. Let us say that something similar happens with the uncreated energy of God. If we were able to unite with the essence of God, we would become gods in essence. Then everything would become a god, and there would be confusion so that, essentially, nothing would be a god. In a few words, this is what they believe in the Oriental religions, e.g. in Hinduism, where the god is not a personal existence but an indistinct power dispersed through all the world, in men, in animals, and in objects (Pantheism). God, according to the Orthodox theological view, is One in a Trinity and a Trinity in One. As St. Maximus the Confessor, St. Dionysius the Areopagite, and other holy Fathers repeatedly say, God is filled with a divine eros, a divine love for His creatures. Because of this infinite and ecstatic love of His, He comes out of Himself and seeks to unite with them. This is expressed and realised as His energy, or better, His energies. With these, His uncreated energies, God created the world and continues to preserve it. He gives essence and substance to our world through His essence-creating energies; He illuminates man with His illuminating energies; He sanctifies him with His sanctifying energies. Finally, He deifies him with His deifying energies. Thus, through His uncreated energies holy God enters nature, the world, history, and human life.”
