Ohhhhhhhh myyyyyyyyyy Gaaaaawwwwdddd....why is there such an obsession with the "end of the world" being incipient? Your guest quotes Revelations, but did he read the part that the end happens over centuries or even millennia? Calm the fuck down. You ain't special. The same thing happened with Y2K - people seemed to think that there was something special because a number on a calendar that was completely made up had a bunch of zeroes on it.
Not that I believe that Revelations is "made up". But believe me, you're not gonna want to be around when those end times really do occur. You don't get a special badge. Live the life given to you in the best way possible - Jesus gives us a lot of great advice in the Gospels if you need guidance - and let this plane of existence live without your worthless worry.
