How do we know that humanity's true problem is sin?

The reality of human sinfulness is a central theme in Scripture. Romans 3:23 tells us that 'all have sinned and fall short of the glory of God.' This foundational truth helps us understand that our primary issue is not just our actions or behaviors but our very nature; we are dead in our trespasses and sins (Ephesians 2:1). The text emphasizes that only through the revelation of God can we truly comprehend our need for redemption. It is crucial to realize that man cannot remedy his condition; he is in desperate need of an external savior, which is met in Jesus Christ alone.
