John 8:24-29

Therefore I said to you that you will die in your sins; for if you do not believe that I am He, you will die in your sins.” Then they said to Him, “Who are You?” And Jesus said to them, “Just what I have been saying to you from the beginning. I have many things to say and to judge concerning you, but He who sent Me is true; and I speak to the world those things which I heard from Him.” They did not understand that He spoke to them of the Father. Then Jesus said to them, “When you lift up the Son of Man, then you will know that I am He, and that I do nothing of Myself; but as My Father taught Me, I speak these things. And He who sent Me is with Me. The Father has not left Me alone, for I always do those things that please Him.”
