It probably makes more sense to say "we believe what the bible means". It seems to be over simplistic to say we believe it is literal because there are parts that are figurative and parts that are typology. God does so much data compressing it is hard to explain how much is really in there.
It should be no object of amazement that they think one can only say Jesus is Lord if they are Spirit filled. They don't realize the true meaning being stated there. A devil worshipper could walk up unbeknownst to them and if he can say 'Jesus is Lord' they'd buy him as a long lost Christian Lamb. They view it all 2 dimensionally - I have Gas therefore I can fuel and drive a car. Well, Duh. That isn't the point. The point is that without the existance of Gas, you couldn't build the car - much less do anything else with it. It's no wonder their priests get their butts kicked in spiritual warfare..
