28 Then Jesus said, “When you lift up the Son of Man, then you will know that I am he, and I do nothing on my own initiative, but I speak just what the Father taught me.
29 And the one who sent me is with me. He has not left me alone, because I always do those things that please him.”
30 While he was saying these things, many people believed in him.
31 Then Jesus said to those Judeans who had believed him, “If you continue to follow my teaching, you are really my disciples
32 and you will know the truth, and the truth will set you free.”
33 “We are descendants of Abraham,” they replied, “and have never been anyone’s slaves! How can you say, ‘You will become free’?”
34 Jesus answered them, “I tell you the solemn truth, everyone who practices sin is a slave of sin.
