The Bible, especially Revelation and Daniel, say the One World Government/New World Order/Beast, has authority to reign and try to destroy the faith of Gods people for 42 months or 1230 days, or 3 1/2 years.
Now as the One world governmnet hasnt began to rule yet, 2012 cannot possibly signal the end.
The Bible says no man knows the date or hour of the end.
But that was written before any of the signs started, ie, once the riegn of the New World Order under the anti-christ starts, you know the end will be in 42 months time.
Now Jerusalem, was under captivity by Babylon, and God people in captivity to such, for a precise period of 70 years.
Often what happens in Old Testament is a pattern for what happens at the end, so, Jerusalem got captured by what Revelation 17 and 18 calls the Great Harlot, Babylon the Great in 1948, 70 years from 1948 is 2018, as Revelation 17 describes Babylon the Great being destroyed by the Beast, or world government, just as the original Babylon was destroyed by the Medes and the Persians, then the 3 1/2 year reign before Jesus second coming has to occur to include 2018.
Further indications that this time period could be the time of the rule of the Biblical Beast include the following where said One World Monetary system is hoped to be in place by 2016.
Tie this in with the Bibles prophesy that the "Beast" will use its monetary power to demand worship whre it states that evry body will have to recieve its "Mark" in order to be able to buy or sell.
My advice therefore, is not to be worried about something you have no control over, but that if you are worried that some of the Bibles coming true, realise therefore that the good bits will also therefore come true, and sotake this time to make sure you get on the winning side of the subsequesnt war between good and bad.One World Currency revealed
