I always stress theosis since most people get blow away when they learn about it for the first time, myself included
Theosis is awesome in the truest and fullest sense of the word. God hid His majesty within His own creation, becoming a man that we might become like Him, reuniting Creator and created in perfection. At the beginning of each Proskomedia, we say the Apoytikion of the Forefeast of the Nativity:
"Rejoice, O Bethlehem; for Eden hath been opened for all. Prepare, O Ephratha; for the Tree of life hath blossomed forth in the cave from the Virgin; for her womb did appear as a spiritual paradise in which is planted the divine Plant, whereof eating we shall live and not die as Adam. Christ shall be born, raising the image that fell of old. "
This is Redemption. This is Salvation. This is Truth.
