John 9:2-5 NIV

[2] His disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” [3] “Neither this man nor his parents sinned,” said Jesus, “but this happened so that the works of God might be displayed in him. [4] As long as it is day, we must do the works of him who sent me. Night is coming, when no one can work. [5] While I am in the world, I am the light of the world.”
