The ascension must first be understood as an element of descent:
8 Therefore it says, “When he ascended on high he led a host of captives, and he gave gifts to men.”
9 (In saying, “He ascended,” what does it mean but that he had also descended into the lower regions, the earth?
10 He who descended is the one who also ascended far above all the heavens, that he might fill all things.)
Thus, references to the ascension must not neglect the incarnation as references:
18 Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit.
19 And her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly.
20 But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit.
21 She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.”
22 All this took place to fulfill what the Lord had spoken by the prophet:
23 “Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel” (which means, God with us).
24 When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife,
25 but knew her not until she had given birth to a son. And he called his name Jesus.
Some observations respecting the eventual ascension. The Holy Spirit superintends the Incarnation: “she was found to be with child from the Holy Spirit”. It is now the Holy Spirit who communicates the ascended Christ to us.
The work of the Incarnation sought the reconciliation: He will save the people form their sins. The work of Christ in the ascension is (in part) to make intercession (Hebrews 9:24).
The work of the ascended Christ begins with the intention of the Incarnation.
