This is a snapshot of a specialized resource called the High Definition New Testament, published by Logos Bible Software. I won’t take the time to explain all of the mark up of the text. Suffice to say that a Greek stud [Steve Runge] went through the New Testament and marked where the Greek is emphasized in different ways.
What I want to get at is the end of the comment by the ex-blind, ex-beggar who had an encounter with Jesus. He is being interrogated by the Pharisees who say “this man [Jesus] is a sinner.”
The ex-blind, ex-beggar’s response is this: “One thing! I know” [and here John builds tension in the text because we are now anticipating what that one thing is], that though I was blind, now I see!”
The Pharisees wanted to argue whether or not Jesus was a sinner, whether or not he was from God, that he in no way could open the eyes of a man blind from birth; but the ex-blind, ex-beggar goes right to the heart of unassailable, eyewitness, participant, experience: “Whatever dudes! You can argue that all you want. Here’s the one thing I know: I was born blind, now I can see.”
Hard to argue with that.
