Original sin is crucial because it explains the need for redemption through Christ and highlights humanity's innate helplessness to reach God on their own.
Original sin, as established in Romans 5:12, shows that sin entered the world through Adam, leading to spiritual death for all humanity. This doctrine is critical for Christians because it illustrates our natural state as sinners, incapable of achieving righteousness apart from God's grace. Understanding original sin helps believers grasp their need for a Savior. As Paul writes, 'For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous' (Romans 5:19). This doctrine not only underscores the seriousness of sin but also magnifies the grace of God that provides reconciliation through Christ, making the gospel message necessary and urgent.
