What does it mean that 'man cannot save himself'?

The declaration that 'man cannot save himself' highlights the total depravity of humanity, as described in Ephesians 2:1, where Paul writes that we were dead in our trespasses and sins. This state signifies that we are incapable of forming a relationship with God or earning our salvation through positive deeds or moral living. Additionally, Isaiah 64:6 teaches that our righteous acts are like filthy rags, emphasizing that no good works can measure up to God’s holiness. Hence, the plea for a Savior recognizes that only through Christ's redemptive work can we attain salvation and reconciliation with God.
