How to convert Christians to atheists in 30 seconds (ironically, using bible)

[Tonus]

The way you live now WILL determine the way you live at the resurrection. Our temporal actions truly do "echo" in eternity. Poorly lived lives do not bring joy even in this life. Why would they in eternity?

Would the afterlife be noticeably different from the current one?  Do you think that our afterlives will be anything at all like our current ones?  Is heaven a place that feels like a real world or city?  Is hell a place that feels like a cavern dug into the earth or a lake that is on fire?  If my afterlife is an echo of my current life, then I'd spend eternity being pretty carefree and happy.  Does that mean I'd be in heaven in spite of my atheism?  Or in something akin to the suburbs of hell, where life really isn't that bad because they keep the undesireables out?

I don't know how to answer your question without understanding the actual circumstances of the afterlife.  This was something that I never saw answered as a theist, and that I've never seen answered since.

3) I have no idea. But if it IS true that our temporal action contributes to a summation of an eternal "echoed" life, then torment in the next life means that you tormented yourself and others in this one.

But there are sinful actions which may not be the cause of torment to others, or which require us to stretch the meaning of 'torment.'  A person who directs porn videos for a living and is a friendly and caring person his whole life... what happens to him?

Hell isn't all or nothing. Read Dante's Inferno.

Is Dante's Inferno considered canon by the Church?  The Bible is either vague on the concept of hell (if you interpret it all as metaphor) or quite clear on the concept (if you interpret it literally).  Jesus' own teaching tended to be all-or-nothing.

4) Nothing is an automatic self-damnation. The "best" child-molesters will suffer a GREAT deal more than the worst drug-addict or gay person. It's not a binary as you might think.

Your descriptions make me think that some parts of hell aren't quite, uh... hellish.  I know that Jesus spoke of some being called "least" in heaven, which means that heaven might also be fragmented along such lines.  So maybe heaven and hell are on a single plane of existence where there are slums at one end leading towards nicer housing until you get to a decent suburban area where it rains just a bit too often, and then there's a big gate separating them from a nice neighborhood where you can keep your doors unlocked, leading up to the classy rich neighborhood that's just a short walk from God's office (whose schedule is always clear because no one complains).

I mean, if the worst slum in hell gets cable TV then maybe eternity isn't so bad, unless all it shows are re-runs of The Apprentice.
