If Jesus is resurrected from the dead, does he already have his human form body?

The answer is actually very simple. Your body depends on location. If you are on Earth you have the kind of body we’re accustomed to see here. If you are in Heavens the body is much different. Resurrection is done by means of relocation. You get a body that belongs in certain location with all that belong to it based on that line of causality. For example, during resurrection Jesus was relocated to the garden of Gethsemane where he had just prayed to the Father. Therefore his body was fully physical, not wounded at all and dressed with appropriate clothes that belonged there despite the fact that before the resurrection his dead body was wrapped in burial clothes only. Not all relocations are like that. Locations can be distant but also very close. When Jesus resurrected Lazarus he relocated his body to an extremely close place which line of causality diverged very insignificantly. Another good case is resurrection of Eutychus by apostle Paul. In the original causality of events he felt from the third floor in a most natural way that would cause him dead on the spot. However, we do understand that a person can also drop down from the same height and despite all odds survive without any serious fall down without any serious injuries. Both outcomes are just different locations with their unique line of causality. Now, if you are resourceful enough you can perform the relocation. Unfortunately, I’m just getting a bit off the topic here, so I’ll not delve into fine details how the relocation is actually being performed. 
So, what I wanted to say is that the body depends on location. If you are resurrected to a place on Earth there is a good chance you will have a material body, but those relocated in the Kingdom of Heaven will posses a far better, superior spiritual body. So the answer is yes! When resurrected, Jesus Christ possessed a perfectly normal physical body as duly belonged to him at that time. So for example, he had a need to eat and he ate. Him appearing inside locked house or suddenly disappearing from sight can also be explained but it is off topic.
