Human bodies are made of cells and molecules and it is very highly likely that some of the molecules in a person's body that make up the cells of that body were once molecules that were in the cells of other human bodies. How then can the exact same dead bodies be resurrected for everyone if over time the dead bodies shared these molecules while on earth?
If one tries to argue that Jesus knows who is going to heaven and therefore, makes sure those people do not share their molecules with any others, then you have the problem of free will and predestination.
What of the person who was born without a leg? Does that person get a new leg when they are resurrected? With what material does that leg get made? There was never an original leg to resurrect. If they do not get a new leg, how is the body perfected? At which stage of life will we be resurrected? If a man dies at age 90, hobbled by age, will he be condemned to live in this state for eternity? If a woman has lost a limb, will she be given a new one on the Day of Judgment? If a person dies as an infant, not yet able to speak, will he be resurrected in a tiny body but given adult faculties?
