As a born again Christain, I feel it is my duty to save sinners from the fires of hell. At work I like to witness to the heathens at every opportunity. I also like to leave little post-it notes in the cubicles with scripture.

Yesterday while witnessing to a heretic he asked me why he should believe what the bible say is true. I responded by quoting the holy bible where it says it's true. He said that was circular logic and that we can't simply claim that the bible is true because it says it is. He added that it was highly unlikely that the bible would say anything else about itself.

Not knowing how to respond I just started throwing more scripture at him. Then he got real irritated with me and said:

"Look, imagine that I owe you $100 and arrive at your doorstep one day telling you that I wish to pay my debt off. I then open my hand and show you $100 in Monopoly money. You look at me in disbelief and tell me that you can't accept it because it's not real money. So I then offer you $500 in Monopoly money but you refuse it as well for the same reason. Then I offer you $1000 in Monopoly dollars and you slam the door in my face.

That's how effective scripture slinging is with non-believers. Please don't be a mere scripture-slinger."

I don't get it. What's his point? What is wrong with using the bible to prove that the bible is true?
