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.
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.
