Sarah Trachtenberg brought up a good point I hadn't thought of before in a comment she left at The Hypatian Shore. Supposedly, Christ died for our sins. Even if you were born and led a godly life, you still were stuck with original sin. So, you can't get into heaven without worshiping Jesus as the one true Son. So, as Sarah pointed out, what happened to everyone who came before Christ? How the hell did they get into heaven?
And while we're on the subject, did everyone killed in the flood go to hell? You would think so - after all, God didn't seem to like them very much. Seems like there have been huge swaths of people denied entrance to the party.
I'm sure the Christians have a convoluted explanation involving the fall and original sin. But I'd like to here one that uses the analogy of God as bouncer and everyone else trying to pay the cover charge.
