John 8:33-36

33“We are descendants of Abraham,” they answered him, “and we have never been enslaved to anyone. How can you say, ‘You will become free’?”

34Jesus responded, “Truly I tell you, everyone who commits sin is a slave of sin.

35A slave does not remain in the household forever, but a son does remain forever.

36So if the Son sets you free, you really will be free.
