John 8:31-34

Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; and ye shall know the truth, and the truth shall make you free. They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free? Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin.
