[Acts 1: 3 
He presented himself alive to them after his suffering by many proofs, appearing to them during forty days (remember 40 days is very significant to the stories)
and speaking about the kingdom of God.
So when they had come together, they asked him, “Lord, will you at this time restore the kingdom to Israel?”
7 He said to them, “It is not for you to know times or seasons that the Father has fixed by his own authority.
8 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.”
9 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.
10 And while they were gazing into heaven as he went, behold, two men stood by them in white robes,
11 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.”]
Wow I read this and I am amazed, that for forty days after he died and resurrected, he appeared to them sharing many things with them.
THEN He was lifted up… right before their eyes. Can you even imagine? Can you even think of how awesome that would have been?
I remember when I have watched a balloon or a kite leave the hands that were holding it, and I watched as it drifted up higher and higher till it can no longer be seen.
Wouldn’t that be both amazing and confusing to see a cloud drift him up higher?
This is JESUS who they were just talking to.
Then two men appeared? Could they have been angels? we aren’t told.
He rose from the dead and left alive, as he moved higher and higher into a space they could no longer see.
How amazing and wonderful this whole story of love is for us.
I cannot imagine this whole scene unfolding.
