John 8:31-36 NIV

[31] To the Jews who had believed him, Jesus said, “If you hold to my teaching, you are really my disciples. [32] Then you will know the truth, and the truth will set you free.” [33] They answered him, “We are Abraham’s descendants and have never been slaves of anyone. How can you say that we shall be set free?” [34] Jesus replied, “Very truly I tell you, everyone who sins is a slave to sin. [35] Now a slave has no permanent place in the family, but a son belongs to it forever. [36] So if the Son sets you free, you will be free indeed.
