John 8:31-36 NRSV
Then Jesus said to the Jews who had believed in him, “If you continue in my word, you are truly my disciples; and you will know the truth, and the truth will make you free.” They answered him, “We are descendants of Abraham and have never been slaves to anyone. What do you mean by saying, ‘You will be made free’?” Jesus answered them, “Very truly, I tell you, everyone who commits sin is a slave to sin. The slave does not have a permanent place in the household; the son has a place there forever. So if the Son makes you free, you will be free indeed.
