21 Again he said to them, "I am going away, and you will search for me, but you will die in your sin. Where I am going, you cannot come." 22 Then the Jews said, "Is he going to kill himself? Is that what he means by saying, "Where I am going, you cannot come'?" 23 He said to them, "You are from below, I am from above; you are of this world, I am not of this world. 24 I told you that you would die in your sins, for you will die in your sins unless you believe that I am he." 25 They said to him, "Who are you?" Jesus said to them, "Why do I speak to you at all? 26 I have much to say about you and much to condemn; but the one who sent me is true, and I declare to the world what I have heard from him." 27 They did not understand that he was speaking to them about the Father. 28 So Jesus said, "When you have lifted up the Son of Man, then you will realize that I am he, and that I do nothing on my own, but I speak these things as the Father instructed me. 29 And the one who sent me is with me; he has not left me alone, for I always do what is pleasing to him." 30 As he was saying these things, many believed in him.
31 Then Jesus 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 slaves to anyone. What do you mean by saying, "You will be made free'?" 34 Jesus answered them, "Very truly, I tell you, everyone who commits sin is a slave to sin. 35 The slave does not have a permanent place in the household; the son has a place there forever. 36 So if the Son makes you free, you will be free indeed. 37 I know that you are descendants of Abraham; yet you look for an opportunity to kill me, because there is no place in you for my word.
38 I declare what I have seen in the Father's presence; as for you, you should do what you have heard from the Father."

Those that live in unbelief, are for ever undone, if they die in unbelief. The Jews belonged to this present evil world, but Jesus was of a heavenly and Divine nature, so that his doctrine, kingdom, and blessings, would not suit their taste. But the curse of the law is done away to all that submit to the grace of the gospel. Nothing but the doctrine of Christ's grace will be an argument powerful enough, and none but the Spirit of Christ's grace will be an agent powerful enough, to turn us from sin to God; and that Spirit is given, and that doctrine is given, to work upon those only who believe in Christ. Some say, Who is this Jesus? They allow him to have been a Prophet, an excellent Teacher, and even more than a creature; but cannot acknowledge him as over all, God blessed for evermore. Will not this suffice? Jesus here answers the question. Is this to honour him as the Father? Does this admit his being the Light of the world, and the Life of men, one with the Father? All shall know by their conversion, or in their condemnation, that he always spake and did what pleased the Father, even when he claimed the highest honours to himself.
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.
