42 Jesus said to them, "If God were your Father, you would love Me, for I proceeded forth and came from God; nor have I come of Myself, but He sent Me. 43 Why do you not understand My speech? Because you are not able to listen to My word. 44 You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it. 45 But because I tell the truth, you do not believe Me.
46 Which of you convicts Me of sin? And if I tell the truth, why do you not believe Me? 47 He who is of God hears God's words; therefore you do not hear, because you are not of God."
Matthew Henry's Commentary on John 8:42-47
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.
