I very common way of disposing of somebody’s earthly remains is to have them cremated and then to dump their ashes in a place that had some significance to them while they were living. Maybe it was a trail on a mountain or at the seashore or just scattered to the wind.
This raises a practical question for one of the things revealed by the Bible–the resurrection of the body. If our remains are scattered or even if they are not, the molecules that made up that body end up as part of the soil and very likely a part of another living being, maybe even another person. Right now, your body could have in it carbon that was a part of an animal, a bug, or possibly several other people. At the resurrection of the dead do we fight for our original molecules?
This is part of a bigger question. What constitutes me? We are not just temporary chemistry with the illusion of having a consciousness. That idea, advanced by hardcore evolutionists, does not match the evidence at all. It feels more like the opposite. That I am a soul that is merely borrowing a body. That idea is common in Eastern religions (Hinduism, Buddhism, etc.) The Bible argues that we are a soul and an earthly body, and I would argue, even a heavenly body.
What is resurrected on Judgment Day, and how can it be me? Throughout our lives we are exchanging atoms with the environment around us. We should not assume personal possession down to the atomic level. What truly distinguishes our physical, earthly self is our DNA. Even our DNA is a flawed blueprint of our earthly being as it contains mutations passed on to us from our original distortion in the Garden of Eden, all our ancestors, and some we have suffered in our lifetime. We are truly not evolving but devolving.
That is why I am skeptical that our resurrection will involve our disposed of remains much or at all. The resurrected body will be raised perfected and indestructible. I expect it will retain many unique qualities that will reflect who we are, but none of the acquired weaknesses and flaws. God retains the design of what we are physically. As Adam was made from the earth, so will we be raised from it. Not necessarily, from the earth of our old bodies, or even in the location. For this reason, choosing a burial place is more a consideration for the living than the dead.
So is it with the resurrection of the dead. What is sown is perishable; what is raised is imperishable. 43 It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power. 44 It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body.1 Corinthians 15:42-44
Assuming that our dead body forms a literal starting point for the resurrected body may be true or may be pushing the biblical analogy of a seed too far. Either way God has the matter in control regardless of where our dead remains end up.
