How do we know that man is fallen and in need of redemption?

The doctrine of man's fallenness can be traced throughout Scripture, as it outlines humanity's departure from God's intended glory and moral perfection. Romans 3:23 states, 'For all have sinned and fall short of the glory of God,' indicating that every person is inherently flawed and in need of redemption. The illustration in Philippians 3 shows that many live in a deplorable state, unaware of their spiritual condition, marked by a lack of desire for God and an embrace of sin. This awareness of sin and the need for a savior is essential for understanding the Gospel’s message and the beauty of Christ's sacrificial love.
