Thanks to those fancy Hollywood movies that utilize a year as a title, or those that have something to do with doom, many people are scared when a date is said to be the end.
However this is repeated many times, and it is quite annoying, whether it is said by an evangelist or not. What if a survivor of a typhoon similar to typhoon Washi (Sendong in the Philippines) was told these things by a group of proselytes, and suddenly got a heart attack out of fear? Tsk, tsk, tsk, isn't that harsh? Anyway, like a friend told me, some survivors were told of these things, then they were given relief goods, but the personal information of the survivors were collected so that they can monitor their attendance to their services every Sunday. And they made the things WAY TOO LITERAL so that the survivors can be indoctrinated. Now that's doomsaying, and it's way scary.
My only suggestion is: why don't they help them WITHOUT using indoctrination. Just because they lost their loved ones doesn't mean they lost their own faith, whatever it is. They can help by doing counseling, stress debriefing, and dress up in heavy and theatrical make-up with gowns and costumes and perform some silly dance for them so that they can regain their confidence. That should do the trick, rather than scaring them to death.
So, mate, stop scaring them! Or you'll get karma.
