In Mark 11:23 Jesus promises his followers they can move mountains if they have faith in God. But have any of us ever done this? If not, do we lack faith? Or, if it is just hyperbole, what actual help are Jesus’ words in knowing what we can and should pray for? And what has any of this got to do with what is going on with Jesus and the Temple in Mark 11? In this episode, Carey’s New Testament Lecturer, Jonathan Robinson, shares some of his research on how this verse has been interpreted, and presents his own interpretation at the Carey College centenary celebrations.
