Behind the various Christian ideas about heaven and hell lies the more basic belief that our lives extend beyond the grave (see the entry on afterlife).

Indeed, despite their profound differences, many Christians (though perhaps not all) and many atheists can presumably agree on one thing at least. If a young girl should be brutally raped and murdered and this should be the end of the story for the child, then a supremely powerful, benevolent, and just God would not exist. An atheist may seriously doubt whether any future compensation would suffice to justify a supreme being’s decision to permit such an evil in the first place. But the point is that even many Christians would concede
