So he prophecied war and natural disasters. Big deal. I think there will be war and natural disasters sometime in the future, and I'm not a prophet. Also, there is such a thing as advertising, even back in those days. When selling this new religion, Christianity, to the heathens, why not inflate Christ's accomplishments (he was already a great man without the miracles and divinity and stuff - if he existed) by claiming all sorts of supernatural powers for him? Like he healed the blind or cured lepers or predicted that an earthquake would destroy Cyprus or something. The heathens, who believed that demons and magic were just as real as rocks and trees, must have been blown away by these ridiculous claims. I mean, the Gospels themselves get progressively more fantastic as we move from Matthew to John, with Christ going from an influential teacher and revolutionary, in Matthew, to the mightiest sorceror in all creation, in John. Nope, Jesus was a prophet only in the sense that he saw things more clearly than most people did at the time, and not because he could predict the future.
