John 8:24-29

I told you that you would die in your sins; if you do not believe that I am he, you will indeed die in your sins.” “Who are you?” they asked. “Just what I have been telling you from the beginning,” Jesus replied. “I have much to say in judgment of you. But he who sent me is trustworthy, and what I have heard from him I tell the world.” They did not understand that he was telling them about his 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 on my own but speak just what the Father has taught me. The one who sent me is with me; he has not left me alone, for I always do what pleases him.”
