Christ ascended to Heaven as man and as God. Once he became a man, being at the same time, as always, perfect God, he never put off His manhood, but deified it, and made it and us capable of apprehending heavenly things. The Ascension is a prophecy of things to come for those who love God and believe in Him in an Orthodox manner. Those who believe and live according to this belief will be in the heavens, in the flesh, with Him, just as He now abides in the Heavens in the flesh. Our flesh and souls will be saved, because Christ made human flesh capable of deification.
