Romans 3:20 Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.
The letter written to the Romans is scathing in many ways because it shows us that we are definitely sinners no matter how good we think we may be!
It also shows us that even though we may follow the rules to the fullest extent, we are still guilty before God because of what goes through our hearts and minds.
Jesus paid for our sin debt a long time ago but without this book we call our bible, we would not know just how much we do owe Him!
