Judgment day is in ten days, on 21 May 2011, according to a group of Christian fundamentalists that run the eBible Fellowship web site. At that time, the rapture will begin. Those who read the Bible and pray for mercy will be saved, while the rest of us will be destroyed along with the Earth on 21 October (2011, I assume).
I have no intention of worshipping a proposed god that would intentionally destroy those who don't read the Bible and pray for mercy. However, if you're unsure about that, I echo the Christian fundamentalists' final recommendation: consider Nineveh, and thank God for negated negative prophecies.
