John 12:34-50

The crowd answered him, "We have heard from the law that the Messiah
remains forever.  How can you say that the Son of Man must be lifted up?
Who is this Son of Man?"  Jesus said to them, "The light is with you for a
little longer.  Walk while you have the light, so that the darkness may
not overtake you.  If you walk in the darkness, you do not know where you
are going.  While you have the light, believe in the light, so that you
may become children of light."

After Jesus had said this, he departed and hid from them.  Although he had
performed so many signs in their presence, they did not believe in him.
This was to fulfill the word spoken by the prophet Isaiah:
        "Lord, who has believed our message,
        and to whom has the arm of the Lord been revealed?"

And so they could not believe, because Isaiah also said,
        "He has blinded their eyes
        and hardened their heart,
        so that they might not look with their eyes,
        and understand with their heart and turn —
        and I would heal them."

Isaiah said this because he saw his glory and spoke about him.
Nevertheless many, even of the authorities, believed in him.  But because
of the Pharisees they did not confess it, for fear that they would be put
out of the synagogue; for they loved human glory more than the glory that
comes from God.

Then Jesus cried aloud: "Whoever believes in me believes not in me but in
him who sent me.  And whoever sees me sees him who sent me.  I have come
as light into the world, so that everyone who believes in me should not
remain in the darkness.  I do not judge anyone who hears my words and does
not keep them, for I came not to judge the world, but to save the world.
The one who rejects me and does not receive my word has a judge; on the
last day the word that I have spoken will serve as judge, for I have not
spoken on my own, but the Father who sent me has himself given me a
commandment about what to say and what to speak.  And I know that his
commandment is eternal life.  What I speak, therefore, I speak just as the
Father has told me."
