31 Then Jesus said to the Jews who had faith in him, If you keep my word, then you are truly my disciples; 32 And you will have knowledge of what is true, and that will make you free. 33 They 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? 34 And this was the answer Jesus gave them: Truly I say to you, Everyone who does evil is the servant of sin. 35 Now the servant does not go on living in the house for ever, but the son does. 36 If then the son makes you free, you will be truly free. 37 I am conscious that you are Abraham's seed; but you have a desire to put me to death because my word has no place in you.
38 I say the things which I have seen in my Father's house: and you do the things which come to you from your father's house.
39 In answer they said to him, Our father is Abraham. Jesus said to them, If you were Abraham's children you would do what Abraham did. 40 But now you have a desire to put me to death, a man who has said to you what is true, as I had it from God: Abraham did not do that. 41 You are doing the works of your father. They said to him, We are true sons of Abraham; we have one Father, who is God. 42 Jesus said to them, If God was your Father you would have love for me, because it was from God I came and am here. I did not come of myself, but he sent me. 43 Why are my words not clear to you? It is because your ears are shut to my teaching. 44 You are the children of your father the Evil One and it is your pleasure to do his desires. From the first he was a taker of life; and he did not go in the true way because there is no true thing in him. When he says what is false, it is natural to him, for he is false and the father of what is false. 45 But because I say what is true, you have no belief in me.
46 Which of you is able truly to say that I am a sinner? If I say what is true, why have you no belief in me? 47 He who is a child of God gives ear to the words of God: your ears are not open to them because you are not from 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.
