Mark 9:6
He did not know what to say, they were so frightened — the fear is the same ecstatic terror as the storm stilling (Mark 4:41) and the resurrection appearance. The disciples' encounter with divine glory produces not understanding but fear. The fear is the appropriate response to genuine theophany — it does not mean the disciples have failed but that they are in the presence of something categorically beyond ordinary experience. The fear is the honest account of what it is like to be human in the presence of the divine.
