Theism is literally childish

[Succubus]

That is not a choice when it is under threat. Hell is a threat, which is not a choice of mutual consent. 

I'm talking about the saved, for whom hell is no longer a threat.

But it is though, it's a constant threat. Even the most devout Christians are not in a constant state of grace, god can at any time cut the power to the force field separating the saved from eternal damnation. All he needs is reasonable suspicion and bang, down go the shields and the hapless twats have to go through the whole business of confessing and penance once more.
And what about the devout but perma-banned Christians? You know, the ones who cussed out the holy ghost, even inadvertently. The poor sods live their lives in a constant state of terror knowing that no matter what, god in his infinite mercy, has destined them to burn in hell. I think this aspect of the Christian story is the most utterly insane, and the competition is fierce.
