Clearly Jesus' body had undergone changes through death and resurrection. It is the same to outer appearance, so far as personal identity
is concerned. The doubting, questioning disciples handle His person, they know His face, they recognize His voice. He eats with them and talks with them and moves in their midst as before. Even the doubter, stubborn in his demand for tangible, physical evidence, is convinced by the feel of his hands that this is indeed Jesus back again. Further, He moves about among them unrecognized till He chooses to be known. Yet this may have been His power over them rather than any changed quality in His person.
But mark that the limitations of space and of material obstructions are gone after the resurrection. He no longer needs to get that body through space by physical strength or management, but seems to go where He will by choosing to be there. He is no longer affected in His movements by the walls of a building or other such material obstruction, but comes and goes at will. The arrangement of the linen cloths in the tomb, as marked so keenly by Peter and John, is significant. They are found lying as they were when enfolding that body, as though He had in rising risen up through them.
Clearly the body is the same so far as personal identity is concerned. But the limitations are gone. The control of spirit over body seems full, without any limitations. As one of us can, in spirit, be in a place far removed as quick as thought, so He seems to have been able to be actually, bodily, where He wanted to be as quickly. All the old powers remain. All the old limitations are gone, never to return. Jesus had moved over to the life side of death. He had gone down into death's domain, given it a death blow, and then risen up into a new Eden life, where neither sin nor death had power to touch. Those forty days were sample days of the new Eden life on earth.
Jesus has become the leader of a new sort of life lived on the earth, mingling in its activities, but free of its power, controlled from above. He asks every one who will to come along after Him. We can, for He has. It is possible, because of Him. We may, for He asks us to. It is our privilege. Let us go.
