I’ve heard the idea of temporary bodies at death discussed both pro and con, that when a person dies, and are immediately in the presence of the Lord, they appear to be in spirit form, hence, the spirit would be without a body. However, in Rev. 6:10-11, referring to Tribulation Saints in Heaven, they ask why has God not avenged their blood on those who dwell on the earth, they are then given white robes to wear for a little season until their fellow servants, who should also be killed, arrive in Heaven. Would this indicate that even though we arrive in Heaven in a spirit form after death we are given some kind of body in which to reside until the Rapture?
This is just an unsupported human opinion. We only think of spirits as being invisible because we can’t see them. Angels are spirit beings and yet when Elisha’s eyes were “opened” he could see them (2 Kings 6:17).
In the story of the rich man and Lazarus (Luke 16:19-31) they could see each other and Abraham as well. The rich man even asked Abraham to have Lazarus dip his finger in some water to cool his tongue.
From these references I’ve concluded that the spirits of dead believers have a form and are visible to each other in heaven and have no need for temporary bodies.
