I would ask if he feels annoyed that we got his name wrong. His name was pronounced "Yeshuar"(Joshua). The Greeks added an s on the end because 'S' denotes males. All male Greek names had an s on the end. The letter 'J' is pronounced as 'Y' in Mediterranean languages. 'H' also had different sounds in different languages and is often a silent letter. Is it better if I just call you the son of man or Messiah?
I would ask what he meant when he said sins against the Holy spirit will never be forgiven? What does that mean?
I would ask if it was him that was wrestling with Jacob, Jacob mistook an angel for his twin brother and wrestled with him, the identity of the being was unknown but he said he saw the face of God when he wrestled with the angel? I am confused.
I would ask Jesus what will happen in the near future. He predicted many things. I would be curious about current events.
I would ask if he visits the Earth in disguise from time to time to see how people are doing, perhaps he appears as an everyday person.
I would ask about paradise, I would ask what it looks like and what do people do when they are there. Would I be allowed to play golf and Tetris in that place.
I would ask him if Satan was always rebellious and why he wasn't thrown into the lake of fire straight away when he was turning against God. Was God being merciful or something like that? I don't know.
