The believer's challenge.
Since there is the blasphemy challenge to demonstrate the atheists belief that there is no proof of God or the Bible, I think it is only fitting that we have a challenge for our bible believing "friends". Again we turn to the gospel of Mark for guidance in this matter:
17And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; 18they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well."
Anyone can fake the driving out demons and speaking in tongues(just say "Should have bought a Honda but I bought a Toyota" really fast).
I want to see the believer's challenge. In places near where Christians gather, let's have a cyanide/arsenic cocktail and a mix of the worlds most deadliest snakes. Let's see who has bigger balls, atheists condemning their souls to external hell or Christians who "believe".
