Why is the doctrine of original sin important?

The doctrine of original sin, rooted in the fall of Adam, reveals that all humanity is born in a state of spiritual death and depravity, as articulated in Romans 3:10-12, which states that no one is righteous, not even one. Understanding original sin is vital because it illustrates why humanity cannot attain salvation through its own efforts or decisions. The scriptures emphasize that without acknowledging this fallen nature, one cannot grasp the depth of the need for Christ’s sacrificial death and the grace provided through Him. Thus, recognizing original sin highlights God's mercy and grace in providing a Savior who redeems fallen humanity.
