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

After the fall, humanity is described in Scripture as dead in trespasses and sins (Ephesians 2:1). This spiritual death signifies a complete separation from God, marked by a loss of understanding and desire for Him. The implications of Adam's sin extend to all mankind, resulting in an inherent sinful nature that cannot seek God without divine intervention. The need for a new heart and true repentance emphasizes the grace of God, which calls believers to restoration in Christ, who alone can regenerate their hearts and reconcile them with God.
