The ability to believe is the most powerful force at mankind’s disposal. Everything that has been done, for good or bad, was done because someone believed it could be or should be done. Every problem that has been solved was solved because someone believed it could be or should be solved.We constantly look for evidence to support what we believe is true. In the case of religious belief, that means if you believe deeply enough any religious system becomes a self-fulfilling prophecy. If that’s true, isn’t it possible that Christianity is just an example of groupthink on a massive scale?
