What does the Bible say about the state of man after the fall?

According to Scripture, particularly Isaiah 5:20-22, after the fall, man fell into spiritual blindness and deafness, losing the ability to see or hear the voice of God. The natural man now walks in darkness, characterized by ignorance and pride. Spiritual darkness leads to a complete inability to distinguish between good and evil, as the fallen man's understanding is darkened. This fallen state results in sin, rebellion, and spiritual death, leaving humanity incapable of performing good works without divine intervention.
