Why is it important for Christians to understand the fall of man?

The fall of man is a foundational doctrine in Christian theology as it explains the origin of sin and humanity's separation from God. This understanding is essential because it frames the need for salvation and the redemptive work of Christ. Without the fall, the significance of Christ's sacrifice becomes diminished. The fall demonstrates our inherent inability to please God and the dire consequences of sin, which are death and separation from Him (Romans 6:23). Moreover, acknowledging the fall leads to a greater appreciation for God's grace and mercy in providing redemption through Jesus Christ, emphasizing the Gospel's core message.
