John 8:31-34

³¹Then Jesus said to the Jews who had faith in him, If you keep my word, then you are truly my disciples;

³²And you will have knowledge of what is true, and that will make you free.

³³They said to him in answer, We are Abraham's seed and have never been any man's servant: why do you say, You will become free?

³⁴And this was the answer Jesus gave them: Truly I say to you, Everyone who does evil is the servant of sin.
