Notice especially that God originally pronounced the curse of death should sin be committed. However, Jesus says in John 8:44 that Satan was a murderer from the beginning. When was the beginning? It had to be when God created beings whose life was in their blood, that is, humans, subject to death if they sinned. This did not occur until Adam and Eve were created. Thus, when they sinned, death had its beginning.
Genesis 3:13 adds, “And the LORD God said to the woman, 'What is this you have done?' The woman said, 'The serpent deceived me, and I ate.'” Thus, from what Jesus says in John 8:44 regarding Satan's part in this episode, we find that God held Satan guilty of murder. His weapon was the deceit that encouraged her to commit sin. She did not completely overlook her respect for God but discounted it enough to give into Satan's persuasion. She did this on the strength of her desire, fueled by her lust for the pleasure of eating the forbidden fruit—but even more so to fulfill her desire to become wise. Then, Adam, though not deceived as Eve was, also discounted God's counsel in order to make sure he did not displease Eve. He was guilty of idolatry.
What does knowing these things accomplish? It shows that, even though their deaths did not occur immediately, at the very least God had delivered the power of death into Satan's hands by means of deceit just before he induced her to sin. Satan used this means to murder them, and he uses this means to this day. Incidentally, Jesus indicates in the Olivet Prophecy, as well as in Revelation, that we will witness a rise in the intensity of deceit just prior to His return.
God did not intervene to stop either Satan or Adam and Eve from following their desires. Adam and Eve had a test to pass. They failed, as have all their progeny. Only Christ has succeeded. Unless one is converted and under Christ's blood, Satan continues to hold this power even to this day. But we are not defenseless; we have Christ to help us in this battle.
