When my turn on the program comes, I am not nervous at all—because all this is happening out of time, out of space. I am, for a moment, a figure of my own fantasy, and I play my appointed role as if I were in the movies.

We often behave as though Jesus is only interested in saving and loving a romanticized version of ourselves, or an idealized version of our mess of a world, and so we offer to him a version of our best selves. With our Sunday school shoes on, we sing songs about kings and drummers at his birth, perhaps so we can escape the Herod in ourselves and in the world around us. But we've lost the plot if we use religion as the place where we escape from difficult realities instead of as the place where those difficult realities are given meaning.

I do the splits perfectly in PE. I lose half a pound in two days. I get the spinach and pig-meat frittata from the lo-carb section for lunch. And no-one else knows. I mentally construct a MyFace status, polishing the memories carefully until they shine. The need to record my life is as fundamental as my need to breathe. Without MyFace, I'm floating. I have nothing to anchor me down, to prove I exist.
