How do we know that all need to be convinced of sin?

Romans 3 and Ephesians 2 assert that there are none who seek after God, and all are dead in sin by nature. This universal state of sin necessitates the Holy Spirit's convincing work, emphasizing that every sinner requires a revelation of their true condition. Without this divine conviction, individuals remain ignorant of their need for the saving work of Christ and are deceived into believing they can stand before God without resting fully in His righteousness. Understanding this is a foundational aspect of Christian faith.
