The Resurrection of the Dead

If my body has decayed and my atoms have gone on to become other things, how will I be reconstituted? What is essentially me in this new resurrection? It's a wonderful question. The image that I've often used is based on two Corinthians five: If you are in Christ and dwelt by the Spirit, you are right now just a shadow of your future self. And presumably which Christ in his resurrected state gives us an image of. Which is why the resurrection appearances are so extraordinary because at the one hand, it is clearly Jesus but on the other hand, it seems to be changed.
