Al Mohler responds:
"I do not believe in God because I have become convinced that his existence is probably true, but because I am convinced that the existence of God is the first principle of all truth. The Christian conviction is not based in probability, but in the assurance of God's existence and self-revelation.
So, in an odd and completely unexpected sense, I am actually thankful for the atheist bus campaign in Britain. When the best atheists can come up with is a message that God probably does not exist, the weakness of the atheist intellectual position becomes clear."
