So yeah, Christianity has some axioms, but it doesn't ask people to merely accept them on faith; that's a mischaracterization. The invitation is to consider (a) how good the evidence really is for your current worldview, and then (b) how good is the evidence for Christianity's truth claims.

Pascal goes one further and suggests considering what you have to gain and lose either way -- which may have been helpful for some when the alternative was mere atheism or unbelief in Christianity, but I disagree that it's helpful in all cases. People coming from Islam have a tremendous amount to lose, including their family, community, livelihood, reputation, and the risk of being condemned eternally by Allah for committing shirk in embracing Christianity, if Islam is true.

I think a better question to ask, whatever someone's background, is "do you want to know the truth, even if it turns out you don't believe it now, and are you willing to follow it no matter what the cost?"

Are you saying the case for Scientology can't fail when considering its internal consistency and correspondence to reality?

I would think its positive case isn't that strong... it's more like an attack chain with an arbitrary payload (including money extraction) for minds with certain vulnerabilities than a coherent set of truth claims (let alone truth claims with at least some evidence in favor).
