John 8:28-32 ESV
So Jesus said to them, “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 authority, but speak just as the Father taught me. And he who sent me is with me. He has not left me alone, for I always do the things that are pleasing to him.” As he was saying these things, many believed in him.
So Jesus said to the Jews who had believed him, “If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free.”
