Mark does not want us to feel comfortable with the closure. Mark shows his brilliance by drawing us to participate in the amazed befuddlement of the women by deliberately confusing us. The closing lines overcome us with a sudden emotional shift.
What kind of ending is that? We do not grasp the resurrection if we are not shocked. We have heard the story too often to be shocked by the empty tomb. I never stop being shocked by the fleeing women. After all, the impertinent young man gave us the order. I am prepared to go and tell someone. I am totally identified with the woman and then they run off like fools. I have the rug pulled out form under me. Just like the women. For a while I am not sure what to say either. I am still waiting for a real ending. Mark is already sitting in the audience with the rest of us.
