John 8:25-30

They said therefore unto him, Who art thou? Jesus said unto them, Even that which I have also spoken unto you from the beginning. I have many things to speak and to judge concerning you: howbeit he that sent me is true; and the things which I heard from him, these speak I unto the world. They perceived not that he spake to them of the Father. Jesus therefore said, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself, but as the Father taught me, I speak these things. And he that sent me is with me; he hath not left me alone; for I do always the things that are pleasing to him. As he spake these things, many believed on him.
