Does the Bible say anything about the doomsday predictions centering around the end of the Mayan calendar on December 2012 or any other future 'end of the world' predictions?
Bible prophecy of the end time talks about a mysterious figure called the Antichrist (also called the "man of sin" and the "false prophet") before the second coming of Christ. But the story starts even earlier.
The Day of the Lord includes a series of cataclysmic events leading up to the return of Jesus Christ and His forceful suppression of humanity's rebellion against God.
