Jesus said to the people who believed in him, "You are truly my disciples if you keep obeying my teachings.
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 on earth. What do you mean, 'set free'?"
Jesus replied, "I assure you that 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 will indeed be free.
