because neither Christ as he is depicted or God wants people to put faith out of fear. They want people to have faith in them of their own initiative, not because of them showing themselves in some miraculous way and making it obvious. Also because, according to the bible, they are eager to reconcile creation. If Christ was on earth for 1000 years before his ascent to glory that would force the appointed time of the end much farther into the future.
So, in perspective of the scriotures, the way things happened would have been the most loving. It allows for the end of sin and suffering to come much sooner in the grand scheme of things.
Too, as far as the statement of, "if he is special prove it" I would argue it has been proven. Even if you don't believe in all the miracles that took place, you'd have to concede the fact that human history after Christ's death was shaped by his life. Western culture has been at the mercy of Christianity for a VERY long time. So to suggest that Christ wasnt a special person, even if you don't accept the existence of God or christs messianic status, is to ignore history itself.
