39 They were indignant. "Our father is Abraham!" 40 And yet here you are trying to kill me, a man who has spoken to you the truth he got straight from God! Abraham never did that sort of thing. 41 You persist in repeating the works of your father." They said, "We're not bastards. We have a legitimate father: the one and only God." 42 "If God was your father," said Jesus, "you would love me, for I came from God and arrived here. I didn't come on my own. He sent me. 43 Why can't you understand one word I say? Here's why: You can't handle it. 44 You're from your father, the Devil, and all you want to do is please him. He was a killer from the very start. He couldn't stand the truth because there wasn't a shred of truth in him. When the Liar speaks, he makes it up out of his lying nature and fills the world with lies.

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.
