Lots of people like that way of thinking. It resolves them of responsibility.
That's something I never understood about xtianity, and especially certain sects within it, like Calvinism. The whole "once saved, always saved" thing never really sat well with me. It's almost funny how they think rapists, murderers, war-mongers, and the like, will get into heaven just for repeating a prayer, while people like MLK, Gandhi, the Dalai Lama, and such, are headed straight to hell.
They only believe that to a certain extent. They think that a certain breed of human is so evil that even praying won't save them. That would obviously include your Hitlers, Charles Mansons, etc... so basically, it's that you have to do good works
and pray to Jeezus (or at least not be an atrocious human being).
As far as fundy beliefs go... eh, it's not the worst. Depends largely on who's talking though. A lot of people could make the words "love thy neighbor" into a negative thing. I don't get it.
Incidentally, that's part of the reason I've always liked Buddhists - they're far more Christian than Christians, in that they tend to be softer-spoken, less aggressive, non-evangelical about their religion, live by example... and seem to be happier and healthier for it. It's an attractive religion and if I could bring myself to believe anything again... it'd likely be that.
