Awkward

So we are all still here on earth and Harold Camping was wrong. This past Saturday I think I thought about it once as an after thought considering I knew that this guy is off his rocker. He has quickly "redeemed" (if you want to call it that) himself by stating that he miscalculated and it will really be Oct. 21, 2011. I would just like him to tell me what the above bible verse means? What is sad is that he claims to be a Christian so this just gives Christians a bad wrap and yet another reason for us to be made fun of.
