I think there is a scripture where Jesus was given power to resurrect himself. Also, Jesus resurrection out of his grave but was did not asend to heaven until later. The JDUBs teach that when Jesus asension happen In Acts his body change(etheral) into the clouds. Because flesh and bones does not go into heavens.
As far as his resurrection, he had power to do what ever he wanted to do but when Marys went to see him he was not prepared to go to heaven as yet and they should not touch him. I just thought I would mention that one.
I know they did not recognize him but he did eat and Thomas touched him so does that mean he was prepared to go into heavens?
It all interesting! one more thing I like the fact that while Jesus was in the grave he preached to the one who were put into darkness.
It is getting late!
