I am glad I get to be reminded how boring my state is. Thanks.
I don't think John was reading the bible. For one, the book's too thin. It would be difficult to cram the entire bible into such a thin book even with small print. Only the new testament might fit in there, which would exclude Leviticus rightaway (although some of Paul's groanworthy stuff on homosexuality would still be in there.) The cover looks kinda soft and bendy too. Not something you'd expect with a bible edition. And John's facial expression is more contemplative than repressed, I'd say.
