Hell, heaven, good, evil, the Bible -- if there's anything we do know about the end of Lost, it's that it definitely has something to do with all those things. The great thing about Lost (despite it being melodramatic and full of textbook network TV cliches) is that it's enjoyable on a number of different levels. The mythology runs so deep and in so many different directions, that you can spend hours analyzing it. But if you don't feel like really geeking out, it's totally enjoyable on a surface level -- with only minimal knowledge of the stories and characters of the Bible. After all, it's not too hard to understand good vs. evil.
For those, though, that are really into how Lost relates to the Bible, USA Today brought in the author of The Gospel According to Lost, Chris Seay, who helped translate some of the recent developments on the show into Bible-speak. For example:
Q: Are Jacob and the Man in Black Jacob and Esau, or God and the Devil?
Biblical Reference: Genesis, Chapters 25-27. Esau was the firstborn son of Abraham's son, Isaac, and his wife, Rebecca. Esau sold his birthright to his twin brother, Jacob, for a bowl of lentil soup. Later, Rebecca helped Jacob, her favorite, pose as Esau to win his dying father's blessing.
Seay: "I'm leaning toward Jacob and Esau, especially after 'UnLocke' alluded to his crazy mother. That would be Rebecca, and she showed favoritism toward Jacob. ... And when the Man in Black tells Richard that Jacob stole his body and humanity, he's equating to what (Esau) was naturally entitled to in that culture with his very nature. It's clear that Jacob has an authority over the island that the Man in Black doesn't have. It's a similar kind of tension."
Oh, and there's more where that came from.
