Which 'me' will God resurrect?

There is a basic complication for Christian views of resurrection and afterlife that I don't see discussed very often.

Suppose I live to be 100 years old. On Resurrection Day, when God gets to my name on the list, God might resurrect 100-year-old me. But why that version of me? Why not resurrect 48-year-old me, or 21-year-old me? If I'm going to be around for eternity, I'd like to be young and healthy!

You get the idea.

But this situation is not unique to me, nor to people who grow old to be 100. What about, say, infants who die prematurely? They seem to be the opposite case.

Let's not suppose that God is arbitrary about which 'me' to resurrect -- but if God isn't arbitrary, what sort of non-arbitrary principle could he apply when making his decision?

One might theorize that there is, for each of us, an essence, or haecceity, and resurrection essentially involves embodying each person's essence. Of course, the soul might just as well fit this role, and perhaps this 'problem' is really the makings of a Christian argument for substance dualism.

Off the top of my head, it doesn't seem as though essences or souls would be of much help. Rather, it would only translate the problem. Instead of the question 'Which physical body do I resurrect?' the question would become 'Which set of properties do I instantiate (by resurrecting which physical body)?' or 'Which body do I put this soul into -- the 21-year-old body or the 100-year-old body?'

In the case of an infant who dies prematurely, it seems particularly clear that even the soul would be of no help in guiding God's decision regarding resurrection, insofar as it seems to represent a sort of worst case scenario in which an infant soul spends eternity in the body of an infant who died prematurely.
