To me a lot of this seems illogical. What seems more logical to me (Duh, as a Baha'i) is that the description of the afterlife that includes the physical body (such as the Bible's description) is not the most accurate representation of life after death. The reason why is because human beings have undoubtedly become more intellectually complex and have gained a greater capacity of understanding through out time. During the time after Jesus' death and when the Bible was written, human beings would not have been able to understand or accept a life "out-of-body".
Throughout God's manifestations, the description of life after death has become increasingly complex, and less dependent on physical identification. The next life will be a life that consists of components we can never imagine, and none of them physical components.

I guess its hard for me to even entertain the idea that something so trivial as our bodies, our physicality, will be necessary in the next life... where our mission to become one with God will eventually be fulfilled.
