John 9:2-7

His followers asked him, “Teacher, whose sin caused this man to be born blind—his own sin or his parents’ sin?” Jesus answered, “It is not this man’s sin or his parents’ sin that made him blind. This man was born blind so that God’s power could be shown in him. While it is daytime, we must continue doing the work of the One who sent me. Night is coming, when no one can work. While I am in the world, I am the light of the world.” After Jesus said this, he spit on the ground and made some mud with it and put the mud on the man’s eyes. Then he told the man, “Go and wash in the Pool of Siloam.” (Siloam means Sent.) So the man went, washed, and came back seeing.
