Isaiah 42:10-13, 16

Sing to the Lord a new song,
    his praise from the end of the earth,
you who go down to the sea, and all that fills it,
    the coastlands and their inhabitants.
Let the desert and its cities lift up their voice,
    the villages that Kedar inhabits;
let the habitants of Sela sing for joy,
    let them shout from the top of the mountains.
Let them give glory to the Lord,
    and declare his praise in the coastlands.
The Lord goes out like a mighty man,
    like a man of war he stirs up his zeal;
he cries out, he shouts aloud,
    he shows himself mighty against his foes.

And I will lead the blind
    in a way that they do not know,
in paths that they have not known
    I will guide them.
I will turn the darkness before them into light,
    the rough places into level ground.
These are the things I do,
    and I do not forsake them. (ESV)

John 9:18-34

The Jews did not believe that he had been blind and had received his sight, until they called the parents of the man who had received his sight and asked them, “Is this your son, who you say was born blind? How then does he now see?” His parents answered, “We know that this is our son and that he was born blind. But how he now sees we do not know, nor do we know who opened his eyes. Ask him; he is of age. He will speak for himself.” (His parents said these things because they feared the Jews, for the Jews had already agreed that if anyone should confess Jesus to be Christ, he was to be put out of the synagogue.) Therefore his parents said, “He is of age; ask him.”

So 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.” He answered, “Whether he is a sinner I do not know. One thing I do know, that though I was blind, now I see.” They said to him, “What did he do to you? How did he open your eyes?” He answered them, “I have told you already, and you would not listen. Why do you want to hear it again? Do you also want to become his disciples?” And they reviled him, saying, “You are his disciple, but we are disciples of Moses. We know that God has spoken to Moses, but as for this man, we do not know where he comes from.” The man answered, “Why, this is an amazing thing! You do not know where he comes from, and yet he opened my eyes. We know that God does not listen to sinners, but if anyone is a worshiper of God and does his will, God listens to him. Never since the world began has it been heard that anyone opened the eyes of a man born blind. If this man were not from God, he could do nothing.” They answered him, “You were born in utter sin, and would you teach us?” And they cast him out. (ESV)
