Sam Harris writes so damn well...
He just posted a debate between Himself and Philip Ball. Here's an awesome short excerpt from it:
Harris: In its most generic and well-subscribed form, Christianity amounts to the following claims: Jesus Christ, a carpenter by trade, was born of a virgin, ritually murdered as a scapegoat for the collective sins of his species, and then resurrected from death after an interval of three days. He promptly ascended, bodily, to “heaven”—where, for two millennia, he has eavesdropped upon (and, on occasion, even answered) the simultaneous prayers of billions of beleaguered human beings. Not content to maintain this numinous arrangement indefinitely, this invisible carpenter will one day return to earth to judge humanity for its sexual indiscretions and sceptical doubts, at which time he will grant immortality to anyone who has had the good fortune to be convinced, on Mother’s knee, that this baffling litany of miracles is the most important series of truth-claims ever revealed about the cosmos. Every other member of our species, past and present, from Cleopatra to Einstein, no matter what his or her terrestrial accomplishments, will (probably) be consigned to a fiery hell for all eternity.
Go, read the debate... it's awesome. One last quote later in the page: "If the basic claims of religion are false, most people are living in a state of abject confusion, beset by absurd hopes and fears, and tending to waste their time and attention—often with tragic results." - Sam Harris
