It will always be difficult to discuss the bible with someone who truly believes the bible was written by God. They will, inevitably prove their point by quoting the bible. But can you use the bible to prove the bible? Probably not, that's when "faith" is brought up and the conversation is basically over.

We were discussing the war and someone quoted Jesus. I personally am inspired by what Jesus said as well as other spiritual revolutionaries. Unfortunately this guy quoted Jesus and expected the argument to be over. It was quiet as everyone considered the latest development in what had been a very spirited conversation. Bones looked the guy, waved him off and said "Jesus was just a hippy on a stick".

There was another awkward silence and then the conversation resumed.
