I've heard and read that when we die, and we go to heaven, we won't have bodies. We'll be spirits only, but so happy that we won't need bodies or objects.

 - In School we were taught that when we go to Heaven, we can have everything we want. Now, that's not possible at all if we're only spirits, and there is no physical world (i.e. an Earth)
 - Doesn't the Bible talk about God's Kingdom, White horses and gates and pearls? I mean, what good is all of that if we can't touch/interact with it (remember, we won't have bodies)?

So this leads me to ask, and I'm not bothered by which denomination I hear about; What is the afterlife _really_ like, according to scripture? Do we _really_ get all that we want? Will we have physical bodies that can interact with things?
