A few years ago, The Edge, U2's guitarist, took his son out trick-or-treating in L.A. Both The Edge and his son dressed in The Edge's trademark black beanie, black leather jacket with a guitar slung around his neck. As they walked away from one door, they heard the couple in the house say, "That's a bit sad, that dad doesn't look anything like The Edge."

The four gospel accounts of Jesus' life are populated by people who have no idea who is standing in front of their eyes. People are oblivious and have no idea of the significance of what's unfolding in front of them.
