John 8:28-32

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. Jesus therefore said to those Jews that had believed him, If ye abide in my word, then are ye truly my disciples; and ye shall know the truth, and the truth shall make you free.
