The Ascension of Jesus happened 40 days after his death.
Have you ever wondered what type of cloud was part of this experience? Was it a cumulus cloud, a stratus cloud, or a Nimbostratus cloud, a cirrus cloud, an anvil cloud, or something else?
I suggest that it was the Holy Spirit in the form of the same type of cloud that Israel had in the desert for 40 years, Numbers 9:15-23. I believe this because Jesus needed to leave so the Holy Spirit could begin his special ministry to followers of Jesus.
John 16:7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
He will come again in glory riding on the Holy Spirit to defeat the evil that prevails in this world.
Again, I suggest you employ Acts 17:11 to make up your mind.
Shalom
