What does the Bible say about man's fallen nature?

According to scripture, particularly in Ephesians 2:1, man is spiritually dead in trespasses and sins due to the fall in the Garden of Eden. This fall did not merely wound man; it rendered him spiritually dead, meaning that every part of his heart—including his mind and will—has been damaged by sin. Total depravity indicates that humanity is inclined to sin and is unable to choose God without divine intervention. This aligns with the biblical teaching that 'no man can come to me except the Father... draw him' (John 6:44), affirming that apart from God's grace, man is hopelessly lost.
