Following the transfiguration experience (Luke 9:28-36), Jesus, with Peter, James and John, trekked down the mountain. The other nine disciples were waiting for them, surrounded by a crowd of people who wanted to see Jesus. One man had come, in desperation, because his only child was constantly in danger from an evil spirit as the boy would often be seized with convulsions. In Jesus' absence, the other disciples had failed to deal with the problem; they were powerless.
