John 8:31-32, 34-36

So Jesus said to the Jews who believed in him, “If you continue to obey my teaching, you are truly my followers. Then you will know the truth, and the truth will make you free.”

Jesus answered, “I tell you the truth, everyone who lives in sin is a slave to sin. A slave does not stay with a family forever, but a son belongs to the family forever. So if the Son makes you free, you will be truly free.
