What device has had the worst possible effect on humankind? The lie! That is, saying something that one knows is not true in order to deceive someone else. And who devised the first lie? Jesus Christ identified “the Devil” as “the father of the lie.” (John 8:44) When did he utter the first lie? It happened thousands of years ago in the garden of Eden. The first human couple, Adam and Eve, were enjoying life in the Paradise that their Creator had provided for them. Then, the Devil entered the scene. He knew that God had commanded the couple not to eat from “the tree of the knowledge of good and bad,” lest they die for their disobedience. Even so, through a serpent, Satan told Eve: “You certainly will not die [the first lie ever told]. For God knows that in the very day you eat from it, your eyes will be opened and you will be like God, knowing good and bad.”​—Gen. 2:15-17; 3:1-5. w18.10 6 ¶1-2
