John 8:33-39

8:33 “We are descendants of Abraham,” they replied, “and have never been anyone’s slaves! How can you say, ‘You will become free’?” 8:34 Jesus answered them, “I tell you the solemn truth, everyone who practices sin is a slave of sin. 8:35 The slave does not remain in the family forever, but the son remains forever. 8:36 So if the son sets you free, you will be really free. 8:37 I know that you are Abraham’s descendants. But you want to kill me, because my teaching makes no progress among you. 8:38 I am telling you the things I have seen while with the Father; as for you, practice the things you have heard from the Father!”

8:39 They answered him, “Abraham is our father!” Jesus replied, “If you are Abraham’s children, you would be doing the deeds of Abraham.
