A theory that bit the dust: (hopefully this hasn't been covered already, I haven't read far back into the thread)..
Jesus only swooned on the cross and was revived in the cool of the tomb.
For this to happen:
1) He had to have survived a spear thrust to the side on top of the brutal beatings before getting on the cross.
So if he somehow survived that..bloodied and beaten with severe blood loss..
2) He had to survive the tightly wrapped linen cloth..mostly dead already. This would usually suffocate any life left.
So if he somehow survived that (getting absolutely ridiculous now)
3) In his severely weakened state He would have had to roll the stone away on the tomb entrance without help.
So let's say He even did that. (Now he is basically God anyway since He can do all this half dead)
4) He has to get past the guards at the tomb who would be executed if they let something happen to the body.
5) Now let's just be stupid and say He got past the guards against all odds.. half dead, exhausted, with alot of blood loss and semi suffocated..
How in the world do the disciples..seeing someone like this.. declare He is risen from the dead?
As a famous scholar said '..Preposterous imagination!'
