fhg is traditional believer. I cannot speak for her, but I am fairly certain she'd mention Hell. I'd probably mention Hell, in the unlikely event I ever got to witness to someone who might be remotely receptive to Christianity 101. what I am trying to get across is...
there's a term I remember from basic sociology...'disenchantment of the world.' as the world modernizes, science and at times pseudoscience become the accepted ways of explaining the world around us. not just biology, either, but psychology....and (more in the EU and UK, not so much in the US, yet) sociology...which is PhDs debunking and deconstructing and analyzing the social order. There's even a "sociology of religion" and "sociology of mental health" (I"m fond of the latter...less fond of the former...). Economics...
its been ongoing for centuries. Foucault writes about the effects of The Enlightenment on the mad/"mentally ill," for instance (confinement, analysis, punishment).

honestly, I think the lack of community bonds and even damage to family bonds (divorce, reduction in importance of extended family, etc.) play a role in this. Personal theory:: in hyper-individualistic, modern, affluent societies, people are just -not- going for traditional Christianity. Even here in the US, where being "Born Again" is still kinda sorta part of the culture in some areas, Barna studies show that even those who go to church regularly are secularized and hold distinctly heretical beliefs about life, faith, God, Jesus, etc....
so, these megachurches (for instance) are often filled with highly entertained, GOP-voting -unbelievers-. I imagine the same goes for smaller churches, but...just think about a US megachurch, with say 5,000 members. If I remember the Barna data correctly, maybe 1/3 of them even hold to the core beliefs that define traditional Christianity. That means about 3,333 of those in the church, rocking out to "contemporary worship music," throwing $$$ in the collection plate, and listening to a megastar minister....
aren't genuinely saved, much less disciple-d, to begin with!
speaking for US culture (yet again), a lot of what one sees here is the demise of 'Cultural Christianity,' which...is what it is.
