John 9:2-7

His disciples asked Him, “Rabbi (Teacher), who sinned, this man or his parents, that he would be born blind?” Jesus answered, “Neither this man nor his parents sinned, but it was so that the works of God might be displayed and illustrated in him. We must work the works of Him who sent Me while it is day; night is coming when no one can work. As long as I am in the world, I am the Light of the world [giving guidance through My word and works].” When He had said this, He spat on the ground and made mud with His saliva, and He spread the mud [like an ointment] on the man’s eyes. And He said to him, “Go, wash in the pool of Siloam” (which is translated, Sent). So he went away and washed, and came back seeing.
