As he passed by, he saw a man blind from birth. And his disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” Jesus answered, “It was not that this man sinned, or his parents, but that the works of God might be displayed 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.” Having said these things, he spit on the ground and made mud with the saliva. Then he anointed the man’s eyes with the mud and said to him, “Go, wash in the pool of Siloam” (which means Sent). So he went and washed and came back seeing. The neighbors and those who had seen him before as a beggar were saying, “Is this not the man who used to sit and beg?” Some said, “It is he.” Others said, “No, but he is like him.” He kept saying, “I am the man.” So they said to him, “Then how were your eyes opened?” He answered, “The man called Jesus made mud and anointed my eyes and said to me, ‘Go to Siloam and wash.’ So I went and washed and received my sight.” They said to him, “Where is he?” He said, “I do not know.”
Before healing the man, Jesus made a general statement about the importance of carrying out the works of God while it was still possible to do so: As long as it is day, we must do the work of him who sent me. Night is coming, when no-one can work.
