John 9:1-5

1And as Jesus passed by, he saw a man who was blind from his birth.

2And his disciples asked him, saying, Master, who sinned, this man, or his parents, that he was born blind?

3Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be revealed in him.

4I must work the works of him that sent me, while it is day: the night cometh, when no man can work.

5As long as I am in the world, I am the light of the world.
