Against God's word, "you will surely die" (Genesis 2:17), the serpent told the woman, "You will not surely die" (Genesis 3:4), and the lie opened the door to the death God had warned of. Jesus traces His opponents' hostility to that beginning: the devil "was a murderer from the beginning, refusing to uphold the truth," and "he is a liar and the father of lies" (John 8:44). Eden is not named, but "from the beginning" (ἀπ᾽ ἀρχῆς, G746) joined to murder (ἀνθρωποκτόνος, G443) and lying points there, with Cain's killing of Abel (Genesis 4:8) as murder's first outworking. The tie is clear, though by allusion. John's context makes it pressing: "you are trying to kill Me, a man who has told you the truth that I heard from God" (John 8:40), the same murder and falsehood now aimed at Christ. Then Jesus answers the serpent's false promise with a true one: "if anyone keeps My word, he will never see death" (John 8:51). The serpent offered life apart from God's word and delivered death; Jesus, who speaks the truth (8:45-46), gives life through His word, a voice worth trusting above every flattering lie.
