“When the Holv Spirit came upon the Virgin and the power of the Most High overshadowed her, the new man was formed in her. He is called new because he was fashioned by God, not in the usual human way, but differently, so that he would become a dwelling of God, not made by human hands. For the Most High does not dwell in places made by hands; not, that is, in dwellings built by human effort.
Then, Wisdom built herself a house (cf. Prov 9:1), and the overshadowing power formed within it an image as a kind of sign. Then, the divine power mixed itself with both the elements of which human nature consists; I mean to say the soul and the body, mixing itself equally with the one and the other.
Both of these elements are subjected to death because of disobedience: for the soul, death consists in separation from true life; for the body it is corruption and dissolution. Of necessity, I say, death had to be driven out through the reuniting of these two elements with life. For just as divinity was united to both of the elements of man, so striking signs of a superior nature will be manifest in both elements.Gregory of Nyssa , On the Resurrection, homily 1, PG 46, 616 B-C.
The Word became flesh is much more than what words can describe. Due to disobedience man died, but the divine power gave him a new life.
