I think I read this only because it's Rob Bell. I like the guy. He's smart, articulate and just plain annoying at points. I don't get half the stuff he says, but that's ok, since I normally toss stuff like that aside anyway.
I think Rob describes how I feel about this book best with something from the epilogue:
For some, hopefully, light has been shed on things that matter, "Oh, that finally makes sense," or "I never thought about it like that," or even, "Huh...I'll have to think about that."
As the title alludes, the book is all about sexuality. It's about sex, God, relationships, marriage, lust, self-image, submitting, Hebrew, heaven, hell, animals, angels, dancing and Johnny Cash. Really...it takes it all on.
