He said in answer, I have no knowledge if he is a sinner or not, but one thing I am certain about; I was blind, and now I see.
Then they put to him the question: Who is the man who said to you, Take it up and go?
So they sent a second time for the man who had been blind and they said to him, Give glory to God: it is clear to us that this man is a sinner.
Then they said to him, What did he do to you? how did he give you the use of your eyes?
The man said in answer, Why, here is a strange thing! You have no knowledge where he comes from though he gave me the use of my eyes.
He who has faith in the Son of God has the witness in himself: he who has not faith in God makes him false, because he has not faith in the witness which God has given about his Son.
