Jesus says: I am the light of the world; anyone who follows me will not be walking in the dark, but will have the light of life.
At this the Pharisees said to him, ‘You are testifying on your own behalf; your testimony is not true.’ Jesus replied: Even though I am testifying on my own behalf, my testimony is still true, because I know where I have come from and where I am going; but you do not know where I come from or where I am going. You judge by human standards; I judge no one, but if I judge, my judgement will be true, because I am not alone: the one who sent me is with me; and in your Law it is written that the testimony of two witnesses is true. I testify on my own behalf, but the Father who sent me testifies on my behalf, too. They asked him, ‘Where is your Father then?’ Jesus answered: You do not know me, nor do you know my Father; if you did know me, you would know my Father as well. He spoke these words in the Treasury, while teaching in the Temple. No one arrested him, because his hour had not yet come. Again he said to them: I am going away; you will look for me and you will die in your sin. Where I am going, you cannot come. So the Jews said to one another, ‘Is he going to kill himself, that he says, “Where I am going, you cannot come?” ‘ Jesus went on: You are from below; I am from above. You are of this world; I am not of this world. I have told you already: You will die in your sins. Yes, if you do not believe that I am He, you will die in your sins. So they said to him, ‘Who are you?’ Jesus answered: What I have told you from the outset. About you I have much to say and much to judge; but the one who sent me is true, and what I declare to the world I have learnt from him. They did not recognise that he was talking to them about the Father. So Jesus said: When you have lifted up the Son of man, then you will know that I am He and that I do nothing of my own accord. What I say is what the Father has taught me; he who sent me is with me, and has not left me to myself, for I always do what pleases him. As he was saying this, many came to believe in him.
