John 9.1-5

As Jesus walked along, 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, ‘Neither this man nor his parents sinned; he was born blind so that God’s works might be revealed 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.’
