John 9:4-7

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.
