John 8:23-28 New Revised Standard Version (NRSV)
23 He said to them, “You are from below, I am from above; you are of this world, I am not of this world. 24 I told you that you would die in your sins, for you will die in your sins unless you believe that I am he.”[a] 25 They said to him, “Who are you?” Jesus said to them, “Why do I speak to you at all?[b] 26 I have much to say about you and much to condemn; but the one who sent me is true, and I declare to the world what I have heard from him.” 27 They did not understand that he was speaking to them about the Father. 28 So Jesus said, “When you have lifted up the Son of Man, then you will realize that I am he,[c] and that I do nothing on my own, but I speak these things as the Father instructed me.
