I think your point is correct as a de facto statement describing many cases, so I'm just going to take issue with one point:
Sort of. The thing is, one needs a certain attitude to get into heaven, and it's impossible to fake that disposition because it consists of humility. For what it's worth I went to a discussion yesterday at the church I'm currently attending where they evaluated the whole concept of heaven and whether or not it's quite the way people imagine. The lecturer was proposing a new, permanent physical realm bereft of pain, rather than the purely metaphysical idea I'm used to. I would pin that attitude of cynical fealty more on Mormons in principle, who have a set list of things to do.
