Do we have no clue that we're just as blind and subjective and selective as "they" are? I think it's good to be reminded of the last couple of lines of John 9. In this chapter, Jesus heals a blind man. The religious elite, the Pharisees, question this man, and the story goes thusly:
They called the man back a second time—the man who had been blind— and told him, "Give credit to God. We know this man is an impostor."
He replied, "I know nothing about that one way or the other. But I know one thing for sure: I was blind . . . I now see."
They said, "What did he do to you? How did he open your eyes?"
"I've told you over and over and you haven't listened. Why do you want to hear it again? Are you so eager to become his disciples?"
With that they jumped all over him. "You might be a disciple of that man, but we're disciples of Moses. We know for sure that God spoke to Moses, but we have no idea where this man even comes from."
The man replied, "This is amazing! You claim to know nothing about him, but the fact is, he opened my eyes! It's well known that God isn't at the beck and call of sinners, but listens carefully to anyone who lives in reverence and does his will. That someone opened the eyes of a man born blind has never been heard of—ever. If this man didn't come from God, he wouldn't be able to do anything."
They said, "You're nothing but dirt! How dare you take that tone with us!" Then they threw him out in the street.
Jesus heard that they had thrown him out, and went and found him. He asked him, "Do you believe in the Son of Man?"
The man said, "Point him out to me, sir, so that I can believe in him."
Jesus said, "You're looking right at him. Don't you recognize my voice?"
"Master, I believe," the man said, and worshiped him.
Jesus then said, "I came into the world to bring everything into the clear light of day, making all the distinctions clear, so that those who have never seen will see, and those who have made a great pretense of seeing will be exposed as blind."
Some Pharisees overheard him and said, "Does that mean you're calling us blind?"
Jesus said, "If you were really blind, you would be blameless, but since you claim to see everything so well, you're accountable for every fault and failure."
