"But perhaps the hope for resurrection and the hope for life after death are not too different."

I think that’s right. The body returns to dust, its individual molecules possibly eventually becoming incorporated in various other people’s bodies. If God is going to reanimate individuals in the resurrection, he has to have some means of storing individual selves separated from their physical bodies. Then when resurrection time rolls around God can reanimate the new eternalized bodies with those same selves that once occupied the corresponding mortal bodies. It’s possible that these individual selves are stored in some static format, like a CD, and until the new body is crafted that can "run" the CD the self remains in a suspended state of potentiality. On the other hand, God could presumably craft a noncorporeal "operating system" that would run these individual selves. After all, God himself presumably lives a noncorporeal yet individuated existence.
