Why do Christians believe in the depravity of man?

The doctrine of human depravity asserts that every person inherits a sinful nature due to the fall of Adam and Eve. Romans 3:23 states, 'For all have sinned and come short of the glory of God,' indicating that sin affects every aspect of humanity, including the will and intellect. This innate depravity means that apart from God's grace, individuals are incapable of choosing God on their own. The historical context of the crucifixion reveals the sinful condition of humanity, which culminated in the rejection and execution of Jesus, the only sinless man. This understanding instills in Christians a deep recognition of their need for a Savior, highlighting the grace and mercy manifested through Christ's sacrificial death.
