Tim Keller writes a book defending the faith entitled The Reason for God. Keller addresses seven objections, which skeptics fire at Christianity.

Exclusivity is the first objections. This objection has been thrown at me when discussing religion with unbelievers. The objectors usually say, with rising blood pressure, something like: “You are arrogant and intolerant to think you are right and all other religions are wrong,” or “Your superior thinking about your religious views is dangerous and detrimental to world peace.”
