Why is understanding man's fallen nature important for Christians?

A clear understanding of man's fallen nature is vital for Christians as it leads to a deeper appreciation of God's grace. Scripture teaches us that due to the fall, humanity is inherently corrupt, with a heart that is deceitful and desperately wicked (Jeremiah 17:9). Recognizing our desperate condition helps us understand the importance of Christ's atoning work, as we see ourselves as completely incapable of achieving holiness on our own. This understanding fosters humility and appreciation for God’s sovereign grace in our lives, motivating believers to rely wholly on God for salvation and spiritual growth.
