From the point of view of the disciples, the events of Holy Week go from joy to terror, from celebration to nightmare. They enter with Jesus, and though they may have been afraid, their fear and trembling in the beginning was in response to awe, and they were full of hope. By the end of the week, their friend has been killed, hung on a cross, and they have scattered, fearing for their own life.
We can understand the emotions of this heavy week, even thousands of years later, going from life to death, and then ultimately to life again. But for a short while, we must sit with the fear and terror of death, the pain of hate, the suffering of the world that Jesus faced. To skip over the nightmare the disciples and Jesus himself experienced would be to skip over the work of Christ on the cross, where death is defeated, where sin does not have the final word.
