John 9:1-4

While He was passing by, He noticed a man [who had been] blind from birth. 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.
