Saw this yesterday on another blog. I have been completely haunted by it. This is Penn, of Penn and Teller, a professed atheist (confirmed atheist? devout atheist? don't know what you call it). He makes a point about evangelism that is the best, most succint reason/ explanation for evangelism I have EVER heard. If you don't have time for the back-story (which is patently un-fascinating) you can skip to 3 minutes in to hear it. The other thing that really struck me is how many times he had to qualify this ONE Christian that he met as 'sane' -- probably said it 5 times. Which leads me to believe that the only other people who have approached this atheist to evangelize, witness, what-have-you, could possibly fall into the 'insane' category.
