Bible shopping and the Romans open-faced sandwich

• What does the book of Romans teach about God's law and human sin?

A host tells how he has been borrowing his wife's Bible, balked at an $85 replacement, and found a circa-1977 Bible dumped at a ministry center. He previews Romans with a corporate compliment-sandwich analogy: Paul's letter is an open-faced sandwich - one piece of bologna under thirty pieces of bread of rebuke.
