Original sin refers to the fallen nature inherited from Adam, which results in all humanity being sinful and separated from God.
Original sin is the doctrine stating that all human beings inherit a sinful nature from Adam, who fell from grace in the Garden of Eden. Romans 5:12 explains that by one man's sin, death entered the world, affecting all humanity. This means that each person is born with an innate sinful disposition, alienated from God and under His curse, as further expounded in Ephesians 2:1-3, where Paul highlights that we were dead in trespasses and sins. Understanding original sin is pivotal as it underscores the necessity of redemption through Christ, who came to reconcile us to God by bearing the curse we deserve.
