John 8:44-47

Ye are of your father the devil Ye are the genuine children of Satan; and the lusts Τας επιθυμιας, the desires; of your father ye will do Namely, resolutely and obstinately, as the words, θελετε ποιειν, evidently imply. The account which Josephus gives of the wickedness of the Jews, about this time, abundantly vindicates this assertion of our Lord from any appearance of undue severity. He was a murderer Greek, ανθρωποκτονος, man-slayer, or man-killer; from the beginning The common term for murderer, in the New Testament, is φονευς. And it seems “not without intention, that the devil, a being not of earthly extraction, is rather called a manslayer than a murderer, as marking with greater precision his enmity to the human race.” Campbell. Satan was a manslayer in inclination, from the beginning of his becoming a devil, and actually such from the beginning of the world: for, from the beginning of the creation, he contrived and designed the ruin of mankind. And he has ever since endeavoured to work their ruin; sometimes by seducing them into sin by his lies, (for as he abode not in the truth, there is no truth in him,) and sometimes by instigating them to kill those whom God sends to reclaim them; as well as in various other ways. Withal, having early departed from holiness and truth, a habit of lying has become perfectly natural to him; and when he speaketh a lie, he speaketh of his own Speaketh what is proper to himself, he being the proper parent, and, as it were, creator of lying. Because I tell you the truth, ye believe me not Ye, his children, disbelieve me, because, instead of soothing you in your sins, and flattering you with lies, I tell you the truth, to which, like your father, you are utterly averse. Which of you convinceth me of sin? Greek, ελεγχει με περι αμαρτιας, which of you convicteth me of sin. The word convinceth is not the proper term in this place; for it relates only to the opinion of the person himself, about whom the question is. But our Lord here, in order to show that the unbelief of his hearers had no reasonable excuse, challenges them openly to convict him, if they could, in any instance, of a deviation from truth or righteousness. As if he had said, Bring evidence of such a deviation, evince it to the world: prove that I have not received my commission from God; or that I have done something to render me unworthy of credit. Show, if you can, that I have taught false doctrine, reproved you unjustly for your actions, or committed sin myself. If you cannot, but must acknowledge that my life is as unreprovable as my doctrine; that the latter is confirmed by the former, and that both are such as become a messenger of God; what is the reason that ye do not believe me? He that is of God, heareth God's words He that is a child of God, humbly receiveth the revelations which God makes of himself by his messengers, hears his words, and obeys his commands, with joy and reverence. Ye, therefore, hear them not Ye reject the revelations, doctrines, commandments, promises, and threatenings, and his word in general, declared by me, his Messenger, and my servants, for no other reason but because you are not his children.
