Yes, "THOSE THAT REMAIN ALIVE"
they are caught up together.
Those that came out of the Ground with Jesus, had to have had their new bodies.
The issue I have is Paul does not give a timing event to what Dead in Christ is. The dead in Christ rise first.
The Dead in Christ raise first.......... Then.......... Then when?
What bodies did the dead have when they walked around with Jesus? Hard to believe they were just skeletons, or were given some temporary body.
My jury is still out on this one.
It is very likely that they were "spiritual bodies", as Paul describes is 1 Corinthians 15 -
It is sown a natural body, it is raised a spiritual body. There is a natural body, and there is a spiritual body. v. 44
The new resurrected body, like Jesus has, seems to be compatible with both heaven and earth.
