Every decision they make, and every vote they cast, is done with this in mind. For instance, there is no reason not to drill all of the oil now, because who are we saving it for? The unsaved, who'll be left behind when the demons roam free? Those heathens can walk.
I am not trying to disrespect anyone's religion (and they're not the only ones with apocalypse fever -- more on that in a moment), but personally, I do think that's kind of weird.
And this affects your life. They -- that is, most people you pass on the street -- believe that the precursor to God tearing open the sky will be a sequence of political and military upheavals in the Middle East, mostly revolving around Israel, and that it is America's role to facilitate those events. And again, they vote accordingly. For example, have you been following the whole situation in Syria? To you it might seem like the Middle Eastern War of the Week, but 1 in 4 Americans thinks that U.S. intervention could lead to the apocalypse, in fulfillment of a prophecy from the book of Isaiah stating that the Syrian city of Damascus would be left in ruins prior to Armageddon. (Note: Islam's prophecy says the opposite.)
