12Again therefore Jesus spoke to them, saying, "I am the light of the world. Whoever follows me will certainly not walk in darkness, but will have the light of life."13Therefore the Pharisees said to him, "You are testifying about yourself; your testimony is not true."14Jesus answered and said to them, "Even if I testify about myself, my testimony is true, because I know whence I came and where I am going; yet you do not know whence I come or where I am going."15You judge according to the flesh; I judge no one.16Yet if I judge, my judgment is true, because I am not alone but I and the Father who sent me.17And in your law it is written that the testimony of two men is true.18I am the one testifying about myself, and the Father who sent me testifies about me.19Therefore they said to him, "Where is your father?" Jesus answered, "You know neither me nor my Father. If you had known me, you would also have known my Father."20These words he spoke in the treasury while teaching in the sacred place, and no one arrested him, because his hour had not yet come.21Therefore he said to them again, "I am going, and you will seek me, and you will die in your sin; where I go you cannot come."22Therefore the Jews said, "Surely he will not kill himself, because he says, 'Where I go you cannot come.'"23And he said to them, "You are from below; I am from above. You are from this world; I am not from this world."24Therefore I said to you that you will die in your sins; for unless you trust that I am, you will die in your sins.25Therefore they said to him, "Who are you?" Jesus said to them, "The beginning, which I also speak to you."26I have much to speak and to judge concerning you, but the one who sent me is true, and I speak to the world the things which I heard from him.27They did not know that he was speaking to them about the Father.28Therefore Jesus said, "When you lift up the son of man, then you will know that I am, and I do nothing from myself, but I speak these things just as the Father taught me."29And the one who sent me is with me; he has not left me alone, because I always do the things that are pleasing to him.30While he spoke these things, many trusted toward him.
