John 8:32-35

32and ye shall know the truth, and the truth shall set you free.

33They answered him, We are Abraham's seed, and have never been under bondage to any one; how sayest thou, Ye shall become free?

34Jesus answered them, Verily, verily, I say to you, Every one that practises sin is the bondman of sin.

35Now the bondman abides not in the house for ever: the son abides for ever.
