The concept of predestination troubles me. I do consider it as graver than any of the other points that separate various churches, because in my opinion it seems to suggest a sadistic god that creates pre-programmed robots, programs some to do evil, some to do good. The robots cannot go against their program, yet at the end of their existence this robot-maker god then puts those he pre-programmed to evil to an eternal torment.
Those of us who go to heck are there for our own fault, it was not God who pre-destined those to go to hell. He KNOWS, but he did not pre-destine them
However, on another note, the title is provocative to Calvinists, somehow suggesting that they will not be going to heaven (which the article does NOT say)
