31 Jesus then said to the Jews who had believed in him, "If you continue in my word, you are truly my disciples, 32 and you will know the truth, and the truth will make you free." 33 They answered him, "We are descendants of Abraham, and have never been in bondage to any one. How is it that you say, 'You will be made free'?" 34 Jesus answered them, "Truly, truly, I say to you, every one who commits sin is a slave to sin. 35 The slave does not continue in the house for ever; the son continues for ever. 36 So if the Son makes you free, you will be free indeed. 37 I know that you are descendants of Abraham; yet you seek to kill me, because my word finds no place in you.
38 I speak of what I have seen with my Father, and you do what you have heard from your father."
39 They answered him, "Abraham is our father." Jesus said to them, "If you were Abraham's children, you would do what Abraham did, 40 but now you seek to kill me, a man who has told you the truth which I heard from God; this is not what Abraham did. 41 You do what your father did." They said to him, "We were not born of fornication; we have one Father, even God." 42 Jesus said to them, "If God were your Father, you would love me, for I proceeded and came forth from God; I came not of my own accord, but he sent me. 43 Why do you not understand what I say? It is because you cannot bear to hear my word. 44 You are of your father the devil, and your will is to do your father's desires. He was a murderer from the beginning, and has nothing to do with the truth, because there is no truth in him. When he lies, he speaks according to his own nature, for he is a liar and the father of lies. 45 But, because I tell the truth, you do not believe me.
46 Which of you convicts me of sin? If I tell the truth, why do you not believe me? 47 He who is of God hears the words of God; the reason why you do not hear them is that you are not of God."
Matthew Henry's Commentary on John 8:31-47
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.
