A woman was visiting the Leaning Tower of Pisa some years ago, and she noticed a man handing a slip of paper to the tourists who parked their cars nearby. He asked, and received, a sum of money from each driver. The tourists thought they were paying for parking.
A woman, who spoke Italian, examined one of the pieces of paper and saw that the man was actually insuring the parked cars against damage in case the tower fell over.
Now, technically, the man was within the law. But he was taking advantage of naive tourists who did not speak the language.
James Whitcomb Riley put it like this: "The meanest man I ever saw, always kep' inside o' the law." And it's true. You can keep the law and still be a scoundrel.
We must be people of high moral character. The cause of Jesus is at stake.
