John 8:25-28

They asked, “Then who are you?” Jesus answered, “I am what I have told you from the beginning. I have many things to say and decide about you. But I tell people only the things I have heard from the One who sent me, and he speaks the truth.” The people did not understand that he was talking to them about the Father. So Jesus said to them, “When you lift up the Son of Man, you will know that I am he. You will know that these things I do are not by my own authority but that I say only what the Father has taught me.
