Iis the world going to end on may 21 2011?

Are you worried? Some people may mock and jear this guy but what he his doing should be a reminder to the world that the day of Christ's return is soon, before his predictions all people were thinking of is which party to go to, which clothes they wanna wear, who is their favorite singer, who said what on twitter, who they spoke with on facebook and a whole lot of materialistic and worldly crap. If youre not a christian then whomever you serve will guide you to your destiny. if you think the world as we know it will never end you have nothing to worry about. how many times the jews expected christ's coming and yet when he was amoungst them they killed him. for generations people has been trying to predict the end of days, the bible for those who believe in it says no man knoweth when God shall appear so even if he does appear as this man tried to predict does that mean he is coming? for ages youve seen and heard people say prepare to me they God, who is your God, are you prepared to meet him?
