Look at the Gospels and make a list of the people who claimed to see him. Notice they are all his supporters. The only one I have noticed who wasn't a supporter was Saul, and he said he saw a bright light and heard voices in his head.
Why didn't Jesus appear before his enemies and prove his point?
It appears that the only enemy he has to prove something to is you.
Again I ask, "What do YOU want for Him?"
