John 9:23-26
English Standard Version
24So for the second time they called the man who had been blind and said to him, "Give glory to God. We know that this man is a sinner."
25He answered, "Whether he is a sinner I do not know. One thing I do know, that though I was blind, now I see."
26They said to him, "What did he do to you? How did he open your eyes?"
