31 Jesus therefore said to the Jews who believed him, If ye abide in my word, ye are truly my disciples; 32 and ye shall know the truth, and the truth shall set you free. 33 They answered him, We are Abraham's seed, and have never been under bondage to any one; how sayest thou, Ye shall become free? 34 Jesus answered them, Verily, verily, I say to you, Every one that practises sin is the bondman of sin. 35 Now the bondman abides not in the house for ever: the son abides for ever. 36 If therefore the Son shall set you free, ye shall be really free. 37 I know that ye are Abraham's seed; but ye seek to kill me, because my word has no entrance in you.
38 I speak what I have seen with my Father, and ye then do what ye have seen with your father.
39 They answered and said to him, Abraham is our father. Jesus says to them, If ye were Abraham's children, ye would do the works of Abraham; 40 but now ye seek to kill me, a man who has spoken the truth to you, which I have heard from God: this did not Abraham. 41 Ye do the works of your father. They said [therefore] to him, We are not born of fornication; we have one father, God. 42 Jesus said to them, If God were your father ye would have loved me, for I came forth from God and am come [from him]; for neither am I come of myself, but he has sent me. 43 Why do ye not know my speech? Because ye cannot hear my word. 44 Ye are of the devil, as [your] father, and ye desire to do the lusts of your father. He was a murderer from the beginning, and has not stood in the truth, because there is no truth in him. When he speaks falsehood, he speaks of what is his own; for he is a liar and its father: 45 and because I speak the truth, ye do not believe me.
46 Which of you convinces me of sin? If I speak truth, why do ye not believe me? 47 He that is of God hears the words of God: therefore ye hear [them] not, because ye are not of God.

Commentary on John 8:30-36
(Read John 8:30-36)
Such power attended our Lord's words, that many were convinced, and professed to believe in him. He encouraged them to attend his teaching, rely on his promises, and obey his commands, notwithstanding all temptations to evil. Thus doing, they would be his disciples truly; and by the teaching of his word and Spirit, they would learn where their hope and strength lay. Christ spoke of spiritual liberty; but carnal hearts feel no other grievances than those that molest the body, and distress their worldly affairs. Talk to them of their liberty and property, tell them of waste committed upon their lands, or damage done to their houses, and they understand you very well; but speak of the bondage of sin, captivity to Satan, and liberty by Christ; tell of wrong done to their precious souls, and the hazard of their eternal welfare, then you bring strange things to their ears. Jesus plainly reminded them, that the man who practised any sin, was, in fact, a slave to that sin, which was the case with most of them. Christ in the gospel offers us freedom, he has power to do this, and those whom Christ makes free are really so. But often we see persons disputing about liberty of every kind, while they are slaves to some sinful lust.
Commentary on John 8:37-40
(Read John 8:37-40)
Our Lord opposed the proud and vain confidence of these Jews, showing that their descent from Abraham could not profit those of a contrary spirit to him. Where the word of God has no place, no good is to be expected; room is left there for all wickedness. A sick person who turns from his physician, and will take neither remedies nor food, is past hope of recovery. The truth both heals and nourishes the hearts of those who receive it. The truth taught by philosophers has not this power and effect, but only the truth of God. Those who claim the privileges of Abraham, must do Abraham's works; must be strangers and sojourners in this world; keep up the worship of God in their families, and always walk before God.
Commentary on John 8:41-47
(Read John 8:41-47)
Satan prompts men to excesses by which they murder themselves and others, while what he puts into the mind tends to ruin men's souls. He is the great promoter of falsehood of every kind. He is a liar, all his temptations are carried on by his calling evil good, and good evil, and promising freedom in sin. He is the author of all lies; whom liars resemble and obey, with whom all liars shall have their portion for ever. The special lusts of the devil are spiritual wickedness, the lusts of the mind, and corrupt reasonings, pride and envy, wrath and malice, enmity to good, and enticing others to evil. By the truth, here understand the revealed will of God as to the salvation of men by Jesus Christ, the truth Christ was now preaching, and which the Jews opposed.
