Why is the doctrine of original sin significant?

The doctrine of original sin is significant as it clarifies the inherent sinful nature of all mankind, stemming from Adam's transgression in the garden (Romans 5:12). When Adam sinned, all humanity fell with him, which means every person inherits a corrupted nature. This doctrine underscores the necessity of divine intervention for salvation, as we are incapable of redeeming ourselves due to our sinful state. It also emphasizes the importance of Christ’s redemptive work, as He provides the only means through which we can be restored to a right relationship with God.
