John 8:28-34 NIV

[28] So Jesus said, “When you have lifted up the Son of Man, then you will know that I am he and that I do nothing on my own but speak just what the Father has taught me. [29] The one who sent me is with me; he has not left me alone, for I always do what pleases him.” [30] Even as he spoke, many believed in him. [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.
