Jesus Heals Man Blind from Birth

"Now as Jesus passed by, He saw a man who was blind from birth.
And His disciples asked Him, saying, 'Rabbi, who sinned, this man or his parents [how could the man sin; he was born that way, he couldn't sin before he was born] that he was born blind?'
Jesus answered, 'Neither this man nor his parents sinned, [this didn't mean they had never sinned, but that sin didn't cause his blindness] but that the works of God should be revealed in him.
I must work the works of Him who sent Me while it is day; the night is coming when no one can work.
As long as I am in the world, I am the light of the world.
When He had said these things, He spat on the ground and made clay with the saliva; and He anointed the eyes of the blind man with the clay.
And He said to him, 'Go, wash in the pool of Siloam [which is translated, Sent].
So he went and washed, and came back seeing.'"

Jesus affirmed that healing reveals the works of God.

Jesus anointed and laid hands on the man's eyes.

Jesus sent the man to wash in the pool of Siloam.

The man obeyed Jesus. He went and washed and came back seeing.
