John 8:30-36

30 As he spoke these things, many believed in him.  31 Jesus therefore said to those Jews who had believed him, “If you remain in my word, then you are truly my disciples.  32 You will know the truth, and the truth will make you free.”

33 They answered him, "We are Abraham's seed, and have never been in bondage to anyone. How do you say, 'You will be made free?'"

34 Jesus answered them, “Most assuredly I tell you, everyone who commits sin is the bondservant of sin.  35 A bondservant doesn't live in the house forever. A son remains forever.  36 If therefore the Son makes you free, you will be free indeed.
