Romans 6 addresses the question of why Christians still struggle with sin despite being dead to it. Paul explains that salvation is a complete reset of the human soul, where we die to our old life and are raised to new life in Christ. This unity with Christ transforms us, freeing us from sin's power rather than giving us license to sin more. Through baptism, we symbolize our death and resurrection with Jesus, and this new identity enables us to live differently. Our unity with Christ becomes the foundation for church unity and gives us victory over sin.
