Most modern Christians have a conception of heaven that is much more Gnostic than Christian. Aristotle and others taught that salvation was "salvation from the body." But the Scriptures teach that salvation is the "salvation of the body" (and indeed of all things pertaining to our humanity.)
Paul taught that Jesus was the "firstfruits from among the dead", meaning that we would follow Christ after the pattern and in the likeness of his resurrection. John taught that someday we will see Jesus and that "we will be just like him." In other words, we, just like Jesus, will have "noses and toe-ses" in heaven.
Bishop N.T. Wright has some very helpful comments on this doctrine in a recent interview with TIME magazine which you can read here.
