John 8: 30 - 39
30: As he spake these words, many believed on him.
31: Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed;
32: And ye shall know the truth, and the truth shall make you free.
33: They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free?
34: Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin.
35: And the servant abideth not in the house for ever: but the Son abideth ever.
36: If the Son therefore shall make you free, ye shall be free indeed.
37: I know that ye are Abraham's seed; but ye seek to kill me, because my word hath no place in you.
38: I speak that which I have seen with my Father: and ye do that which ye have seen with your father.
39: They answered and said unto him, Abraham is our father. Jesus saith unto them, If ye were Abraham's children, ye would do the works of Abraham.
2 peter 2: 19
19: While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage.
