Final answer:
In Genesis 3, Satan appears to Eve as a serpent and deceives her into eating from the Tree of Knowledge, asserting she will not die but will gain divine knowledge, leading to the Fall of Man.
Step-by-step explanation:
Satan first appears to Eve in the form of a serpent in the biblical account of the Fall of Man, found in Genesis 3. This cunning creature engages Eve in conversation, contradicting God's previous command by asserting, "You will not surely die," and suggesting that eating from the Tree of Knowledge will make her like God, knowing good and evil. The serpent's persuasive argument leads to Eve and subsequently Adam eating the forbidden fruit, an act that results in their banishment from the Garden of Eden and the inheritance of original sin by all mankind.
The scriptures highlighted here reflect the serpent's craftiness and the ensuing dialogue with Eve, illustrating the theme of deception and the introduction of sin into the human experience. The passage also provides a foundation for much theological discourse regarding the nature of sin, free will, and the reasons for human suffering in various interpretations of Christian doctrine.
