João 12:35-50 - Bíblia Online

Jesus said to them, For a little time longer the light will be among you; while you have the light go on walking in it, so that the dark may not overtake you: one walking in the dark has no knowledge of where he is going. 
In so far as you have the light, put your faith in the light so that you may become sons of light. With these words Jesus went away and for a time was not seen again by them. 
But though he had done such a number of signs before them, they still had no belief in him: 
So that the words of the prophet Isaiah might come true, when he said, Lord, who has any belief in our preaching? and the arm of the Lord, to whom has it been unveiled? 
For this reason they were unable to have belief, because Isaiah said again, 
He has made their eyes blind, and their hearts hard; for fear that they might see with their eyes and get knowledge with their hearts, and be changed, and I might make them well. 
(Isaiah said these words because he saw his glory. His words were about him.) 
However, a number even of the rulers had belief in him, but because of the Pharisees they did not say so openly for fear that they might be shut out from the Synagogue: 
For the praise of men was dearer to them than the approval of God. 
Then Jesus said with a loud voice, He who has faith in me, has faith not in me, but in him who sent me. 
And he who sees me, sees him who sent me. 
I have come as a light into the world, so that no one who has faith in me will go on living in the dark. 
And if any man gives ear to my words and does not keep them, I am not his judge: I did not come to be judge of the world but to give salvation to the world. 
He who puts me on one side and does not take my words to heart, is not without a judge: the word which I have said will be his judge on the last day. 
For I have not said it on my authority, but the Father who sent me gave me orders what to say and how to say it. 
And I have knowledge that his order is eternal life: so that the things which I say, I say them even as the Father says them to me.
