Or as some have called it, a “glorified physical body.”
For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:21 Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.” (Philippians 3:20-21)
So it's not the loss of humanity but the loss of the earthy body that makes for the through the wall stuff.
But where did the food go?
I think we tend, whatever we tell ourselves, to think of the spiritual as attenuated,whispy. But maybe a spiritual body can do things with matter that are more amazing that what physical bodies can do.
