Mark Vernon trained to be an Anglican priest before losing his faith to become an atheist. But he became disenchanted with that position too. Now he champions agnosticism. He says agnosticism is more than "sitting on the fence" and is a rich place of searching after the big questions.

Church Pastor David Robertson debates with Mark on whether God is ultimately unknowable. David claims that Jesus has made God knowable and that a journey of searching only makes sense in order to arrive at knowing.
