It was not the mere announcement of a principle. Every principle He delivered embodied itself in an act. He added immediately: '_I must work the works of Him that sent me, while it is day: the night cometh, when no man can work. As long as I am in the world, I am the light of the world_.'

But there is a sorrow for Him who is about to impart joy. His countrymen had taken up stones to cast at Him. He has a vision of a time when they would have their way. The light for a while would be quenched. But as long as He was in the world, He must illuminate it.

He went therefore, and washed, and came seeing._'
