Stream of consciousness time:
I've been through some painful physical ailments, I don't want any of that back. The answer, our resurrected bodies are perfect, you won't have those pains. Well I wouldn't have those pains as a spirit either.
If I remained as a spirit I wouldn't have the joys of having a body. What of the concept that we can only experience pleasure as a direct result of being acquainted with pain? If you remove pain from the equation would an eternity of time stretching before us make us eventually forget about the pains and thus ultimately forget pleasures as well? How is that any different from life as a spirit?
Am I talking myself into a belief of reincarnation?

So I find myself wondering, where did the desire to have a continued corporal existence come from? A lack of imagination that consciousness can exist independent of a body; fear of an unknown, a desire to put everything back together just as it is now (except without all that illness stuff); to be able to procreate/populate, I'd venture that entities with bodies beget entities with bodies, entities of spirits beget entities of spirit, but that reflects a limited view; was it added to the narrative of Christ to solidify an argument for life after dead (See, he has a body, a body. It leaves no doubt.), etc.
