Jesus is the Light of the world, the light of life is in Him, His light gives sight to both that are physically and spiritually blind,

He spat on the ground and made paste and pasted it on the blind man and said, Go and wash at the pool of Siloam[Sent],

The blind man was sent and he went and washed and he saw,

He cooperated fully with the word of God. He put his faith to work.
