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.
Matthew Henry's Commentary on John 8:42-44
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.
