I'm not sure I've ever read a book so short and yet so powerful as Sam Harris'
Letter to a Christian Nation.
This took me 90 minutes to read. There isn't a person out there I wouldn't recommend this book to. For the non-believers, Harris offers some nice ammunition to use next time you're stuck in a situation where you want to slam your head against a desk while trying to explain to a Christian why you find their beliefs so appauling. Christians (or really anyone with strong religious views) might benefit from seeing a window into some of the logical shortcomings and societal downfalls that stem from such strong, unprovable beliefs.
From page 67, "It is time that we admitted that faith is nothing more than the license religious people give one another to keep believing when reasons fail. While believing strongly, without evidence, is considered a mark of madness or stupidity in any other area of our lives, faith in God still holds immense prestige in our society."
I will personally ship my copy of this book to the first of you regulars to request it, provided a.) you will most certainly read it with an open mind and b.) you believe you will spend eternity in fire without faith in Jesus Christ. Just PM me your address and it will be shipped within hours.
