Ascension language is enthronement language. Jesus ascending into heaven means that Jesus is now enthroned in heaven. Notice how many times Jesus tells the disciples (us) to stop focusing on earthly kingdoms and glory and to focus instead on the Spirit-empowered mission (and the coming of the same Spirit) that lay before them (us) — to be witnesses in all the world. When the angels "interrupt" their wondering gaze, they also redirect the disciples to continue in this mission by waiting for the coming of the Spirit in Jerusalem.
Here are the readings for Ascension Day and a Prayer for Asscension Day
1 In my former book, Theophilus, I wrote about all that Jesus began to do and to teach 2 until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen. 3 After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God. 4 On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. 5 For John baptized with[a] water, but in a few days you will be baptized with the Holy Spirit.”
6 Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”
7 He said to them: “It is not for you to know the times or dates the Father has set by his own authority. 8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”
9 After he said this, he was taken up before their very eyes, and a cloud hid him from their sight.
10 They were looking intently up into the sky as he was going, when suddenly two men dressed in white stood beside them. 11 “Men of Galilee,” they said, “why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven.”
1 Clap your hands, all you nations;
shout to God with cries of joy.
2 For the Lord Most High is awesome,
the great King over all the earth.
3 He subdued nations under us,
peoples under our feet.
4 He chose our inheritance for us,
the pride of Jacob, whom he loved.
5 God has ascended amid shouts of joy,
the Lord amid the sounding of trumpets.
6 Sing praises to God, sing praises;
sing praises to our King, sing praises.
7 For God is the King of all the earth;
sing to him a psalm of praise.
8 God reigns over the nations;
God is seated on his holy throne.
9 The nobles of the nations assemble
as the people of the God of Abraham,
for the kings of the earth belong to God;
he is greatly exalted.
15 For this reason, ever since I heard about your faith in the Lord Jesus and your love for all God’s people, 16 I have not stopped giving thanks for you, remembering you in my prayers. 17 I keep asking that the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better. 18 I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, 19 and his incomparably great power for us who believe. That power is the same as the mighty strength 20 he exerted when he raised Christ from the dead and seated him at his right hand in the heavenly realms, 21 far above all rule and authority, power and dominion, and every name that is invoked, not only in the present age but also in the one to come. 22 And God placed all things under his feet and appointed him to be head over everything for the church, 23 which is his body, the fullness of him who fills everything in every way.
44 He said to them, “This is what I told you while I was still with you: Everything must be fulfilled that is written about me in the Law of Moses, the Prophets and the Psalms.”
45 Then he opened their minds so they could understand the Scriptures. 46 He told them, “This is what is written: The Messiah will suffer and rise from the dead on the third day, 47 and repentance for the forgiveness of sins will be preached in his name to all nations, beginning at Jerusalem. 48 You are witnesses of these things. 49 I am going to send you what my Father has promised; but stay in the city until you have been clothed with power from on high.”
50 When he had led them out to the vicinity of Bethany, he lifted up his hands and blessed them. 51 While he was blessing them, he left them and was taken up into heaven. 52 Then they worshiped him and returned to Jerusalem with great joy. 53 And they stayed continually at the temple, praising God.
Prayer for Ascension Day
Almighty God, whose blessed Son our Savior Jesus Christ ascended far above all heavens that he might fill all things: Mercifully give us faith to perceive that, according to his promise, he abides with his Church on earth, even to the end of the ages; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, in glory everlasting. Amen
