I agree to disagree to to the comments that God is not in the BB house.
I think God is everywhere, yes even in the BB house. I think that God will listen to what God listens to all the time. Just because they are stuck in that house, I do think God is with them all. 
Blondie, I agree with you - God is everywhere. What gets to me is the folks who expect that God is going to "fix" things for them to win because they profess Christianity. Or because they read their Bible. Or because they say a bajillion prayers.
I believe their prayers are heartfelt. But God isn't a genie in a bottle that you can call on for three wishes. He doesn't make bad things happen to "his" (actually THEIR) enemies. In fact, He plays things out even-handedly. (Mt 5:14 for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. )
What I REALLY want to see is for a Christian* to get on that show - AND ACT LIKE A CHRISTIAN. And no, I don't think the game FORCES you to lie or double-deal. It *might* be easier to win that way - but I don't think it's impossible, and I don't even think it would be hard for someone that was committed to playing it the "honest" way if they were living that as their life.
*not trying to be a religious bigot - could be any person who LIVES the tenets of their religion, instead of mouthing some platitudes to the fairy "God" mother.
