Old story:
A medieval traveler, wandering across the country, comes across a huge construction project. Near his path, he sees three stone masons, hard at work with their hammers and chisels.
“What are you doing?” asks the traveler.
“Breaking stones,” grunts the first.
“Making a wall,” says the second.
“Building a cathedral!” proclaims the third.
Is there any difference in the work of these three men? Maybe not. But is there any difference in their hearts? Certainly yes.
