A spirit does not have flesh and BONES. No mention of blood or using it as proof of Hi being Himself.
This body of flesh, this shell we inhabit must DIE for us to get a new one. It is not the same substance even thought it looks the same. Appearances are appearances.
Just because the appearance is the same, does not mean the inherent substance is the same. Any body would have to be inherently changed in order to be taken up into the sky or heavens. These bodies we have could not survive that.
What happens to the old one?
"It is not the same substance even thought it looks the same. Appearances are appearances."
Are you saying you do not believe in the resurrection of the body, but just something that looks like it?
