28So Jesus said, When the Son of man has been lifted up by you, then it will be clear to you who I am, and that I do nothing of myself, but say as the Father gave me teaching.
29He who sent me is with me; he has not gone from me, because at all times I do the things which are pleasing to him.
30When he said this a number came to have faith in him.
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.
