The Ascension of the Lord is a sacred day on which Jesus ascended into heaven and is now seated at the right hand of God the Father. The great mystery of this day, and the reason it is of such importance, is that he ascended not only as God but as man – ascending in his physical human body. Our human nature has therefore been raised to the dignity of heaven, and this is a sign and a promise that we can follow where he has gone before us.

Acts 1:6-11

So when they had come together, they asked him, “Lord, will you at this time restore the kingdom to Israel?”

He said to them, “It is not for you to know times or seasons that the Father has fixed by his own authority. But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.”

And when he had said these things, as they were looking on, he was lifted up, and a cloud took him out of their sight. And while they were gazing into heaven as he went, behold, two men stood by them in white robes, and said, “Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven.”
