John 8:32-36

And you will know the truth, and the truth will set you free.” “But we are descendants of Abraham,” they said. “We have never been slaves to anyone. What do you mean, ‘You will be set free’?” Jesus replied, “I tell you the truth, everyone who sins is a slave of sin. A slave is not a permanent member of the family, but a son is part of the family forever. So if the Son sets you free, you are truly free.
