What does the Bible say about the condition of sinners?

In Isaiah 64:6, the Scriptures declare, 'We are all as an unclean thing, and all our righteousnesses are as filthy rags.' This illustrates the state of humanity before God. We are described as being without soundness, filled with wounds and bruises, and it's a reflection of our spiritual condition. Just like the Gadarene demoniac in Mark 5, we find ourselves often dead in sin, unable to save ourselves. Our condition is that of spiritual death, dwelling in darkness, until God, who is rich in mercy, speaks life into our dead souls (Ephesians 2:1-5).
