42 Jesus said unto them, If God were your Father, ye would love me: for I came forth and am come from God; for neither have I come of myself, but he sent me. 43 Why do ye not understand my speech? [Even] because ye cannot hear my word. 44 Ye are of [your] father the devil, and the lusts of your father it is your will to do. He was a murderer from the beginning, and standeth not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father thereof. 45 But because I say the truth, ye believe me not.
46 Which of you convicteth me of sin? If I say truth, why do ye not believe me? 47 He that is of God heareth the words of God: for this cause ye hear [them] not, because ye 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.
