The Fall of Man provides insights on a number of levels. The saga begins with a question, initiated with an unexpected conjunction: “Yea,” typically used to join two thoughts, the first of which is evidently unrecorded.
It is as if Satan has already engaged Eve in pleasant dialogue, providing a positive context in which to highlight an apparent contradiction. Aligning himself with Eve, isolating her, befriending her, disarming her, this is all tactical, the art of war: the enemy isolates us, aligns as a friend, then destroys.
It’s likely Eve’s first mistake, to engage without Adam, without God, to neglect her spiritual community and tangle with Satan alone. We learn from Eve: engage the Devil in no conversation, give him no ear or audience. Bring God and others into the equation immediately; ignore the enemy and resist by drawing near to God. (Ja 4:7-8a)
This first word, Yea, is the Hebrew אַ֚ף (’ap̄), although, an adversative contrasting one idea with another, comparing two opposing thoughts in the form of a question: “Yea, hath God said, Ye shall not eat of every tree of the garden?” (Ge 3:1) Satan draws attention to God’s command as an opposition, something holding Adam and Eve back from something good. It is Satan’s way: position God and His Law as the adversary. (Ro 7:22)
The question itself seems innocuous enough; Satan asks Eve to affirm God’s only command, a restriction placed on herself and Adam, which she actually does inaccurately; Eve adds to God’s command an additional prohibition: “neither shall ye touch it.” (2-3) She only has one law to consider, which she fails to recall correctly. She is not yet fallen and remains innocent, yet she is inexperienced, ignorant, naive and careless. We ought not so to be. (1Co 14:20)
Whether this is Adam’s indiscretion in teaching Eve, or Eve’s own carelessness, it’s weakness which Satan is all too eager to exploit. If he convinces Eve to touch the tree and she sees no harm, perhaps eating of it will do no harm either. More instruction in spiritual warfare: Don’t add to God’s Word, and don’t shorten it. (De 12:32) Know the Word, by heart, and like Jesus (Mt 4:4) be ready always to take the sword, the sword of the Spirit, quoting it in context to address temptation, so God’s Way is clear.
The dialogue then leads to Satan’s explicit claim: “Ye shall not surely die: for God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.” (4b-5) It is a two-part claim:  God’s not good and can’t be trusted;  breaking His command will go well for you. Satan accuses God of lying, of having ulterior, malicious motives in giving us His laws, and promises benefit in disobeying God. Satan accuses God of doing exactly what he himself is doing in order to get us to turn against God. It doesn’t really matter which law we break if we do it willfully, the result is the same. (He 10:26-27)
Satan comes as benevolent, spiritual, an angel of light, and his ministers as holy men. (2Co 11:13-15) He offers freedom from God’s Law, freedom to disobey, and lies about the consequences. He started way back in the Garden and hasn’t changed. To overcome, we must hold to the goodness of God, believing all His Laws are for our good (1Ti 1:8), obey Him and submit to Him.
