Imagine yourself in an upstairs room. Jesus' disciples are gathering there, speaking in hushed voices. A table is laid out for the Passover feast. Jesus appears and insists on washing your dirty feet, just like a slave.
Then he invites everyone to sit down to begin the supper. He lifts up a loaf of bread and says, "I break this bread, as I give my body will be broken. Let everyone share in it."
He raises a cup of wine and says, "I pour out this wine for you, as my blood will pour out when they hang me on the cross. I do this out of love and forgiveness. Let everyone share in it. Do this to remember me."
Then Jesus is heading out the door, leading the bewildered group down out of the city, across the Kedron valley, and up the hill again into a garden called Gethsemane. "Watch and wait," he says.
