John 9:4

As he passed by, he saw a man blind from birth.

His disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?”

Jesus answered, “This man didn’t sin, nor did his parents, but that the works of God might be revealed in him.

While I am in the world, I am the light of the world.”

When he had said this, he spat on the ground, made mud with the saliva, anointed the blind man’s eyes with the mud,

and said to him, “Go, wash in the pool of Siloam” (which means “Sent”). So he went away, washed, and came back seeing.
