"Why are Christians so bent on airing their views? Many Christians are actually told that it doesn't matter that they lack reasoning skills, or that they know little about other religious and philosophical worldviews. All that matters is that they know the truth of the Bible, and this is apparently reason enough for people to listen to them whether or not they are making much sense. They are not to be shy about inviting themselves even into arenas of debate where they are clearly in above their heads. Such persons imagine that they are bringing God's truth into the discussion, when in reality all they are doing is confirming to everyone involved that there must surely be a relationship between simple-mindedness and Christian belief.

One might think that this only proves that the Bible does make people irrational. For since the Bible claims to be the truth, even the authoritative word of God, people who believe they have the truth will naturally want to impose it upon everyone else. Such a person has little use for the process of reasoning because all that matters to him is the bottom line. He has already looked up the answer in the back of the book; why then the need to show his work? Everyone is just supposed to take his word for it."
