You, gt, have said this:
Jesus DID NOT have a body with nail scars in it BEFORE He became flesh. His RESURRECTED body did.
Jesus' body was RAISED FROM THE DEAD, not unlike Lazarus was raised; except Jesus had something more going on with himself---he ascended to the Father and was given a RESURRECTED SPIRITUAL BODY. That body is the body he had before coming to earth. He is the First and the Last. WE ARE SAVED THROUGH HIS BODY. We are PUT IN his body as our being saved and reconciled to God. Jesus had that body FIRST AND THE WHOLE CREATION WAS MADE THROUGH THAT BODY.
Lazarus and others were raised after dying, but they were raised with, and kept, the body that will die again.
When we are raised at the resurrection, we will be given a new kind of body. We will not just be raised with our old body.
