Maybe this is a bit quibbling, but I'm curious why my answer was changed to a comment on this question? I did use the previous person's answer as a bit of a springboard, but my answer (John was given a vision of the kindgom of God prior to his death) seemed to be quite different than the other user's (John may still be alive somewhere and could be until Christ's return).
As a meta-meta aside, maybe: Is this the proper way to ask these kind of things?
