Why is understanding man's depravity important for Christians?

The doctrine of total depravity is foundational in Reformed theology, encapsulating the idea that every aspect of humanity is affected by sin. As illustrated in Jonah's flight from God, human beings inherently reject God's authority and flee from His presence. Romans 3:10-11 affirms this by stating that there is none righteous, no, not one; none seeks after God. Recognizing our total depravity not only deepens our comprehension of the necessity for salvation by grace alone but also enriches our appreciation for God's mercy towards us in Christ. As believers grasp the depth of their need, they are led to fully depend on God's grace for their salvation.
