Satan the Devil is the ultimate source of falsely called knowledge and the perpetuator of anti-God philosophies throughout time. Gnosticism stands as one of the many heresies he employs to deceive the whole world. In his first message to mankind in the Garden of Eden, he introduces three core heresies that have persisted through history. The first heresy sows seeds of doubt about God's trustworthiness. With his initial words to Eve, questioning whether God indeed said certain things, he instills a sentiment that God's Word is suspect. This distrust is evident in Gnosticism, where knowledge is valued over Scripture, relying instead on personal experiences, teachings of elders, or insights from angels, astrology, or alchemy. This same skepticism undermines faith by casting doubt on the legitimacy of God's Word, making it subject to human whims and thus untrustworthy. The second heresy, declared by satan as "You shall not surely die," promotes the idea that humans are already immortal, negating the true consequence of death. This lie, reflected in Gnostic dualism of flesh and spirit, portrays the flesh as evil and the spirit as good, with death seen as liberation. Such a belief diminishes the urgency to live according to God's desires, as immortality is assumed, reducing the motivation to resist carnality or to grow spiritually. The third heresy suggests that by taking knowledge of good and evil, humans can be like God, determining right and wrong for themselves. Satan places emphasis on knowing over living eternally, contrasting with a life of submission to God's defined standards. Gnostics pursue mystical knowledge, believing it holds the key to eternal life through advancing into the spiritual realm. This rejection of God's standard fosters antinomianism among Gnostics, who resist laws or standards that conflict with their own, establishing personal codes of conduct over divine commandments. These three heresies, recycled since Creation, subtly undercut God's truth and plan for mankind, manifesting in Gnosticism and every anti-God system of belief. They continue the separation from God begun in the Garden, promoting self-centeredness over outgoing concern, and prioritizing knowledge over faith, hope, and love as defined by God's way.
