The "Father of Lies" is often referred to as the devil or Satan in the context of religious scripture, particularly in Christian theology. The phrase originates from the Bible, specifically in the Gospel of John, where Jesus mentions that Satan was a liar from the beginning and the father of lies. This title emphasizes the devil’s role in promoting deceit and evil. In literature and popular culture, figures like the devil frequently embody cunning, treachery, and manipulation. The concept also extends to discussions about morality, truth, and the nature of evil, serving as a cautionary tale against falsehoods and the destructiveness of deception.
