Sociologist Robert Wuthnow of Princeton University has explored how it is that people make everyday ethical decisions. Many people, he found, perform deeds of compassion, service, and mercy because at some point in their past someone acted with compassion toward them. He wrote, "The caring we receive may touch us so deeply that we feel especially gratified when we are able to pass it on to someone else."

He tells the story of Jack Casey, who was employed as an emergency worker on an ambulance rescue squad. When Jack was a child, he had oral surgery. Five teeth were to be pulled under general anesthetic, and Jack was fearful. What he remembers most, though, was the operating room nurse who, sensing the boy's terror, said, "Don't worry, I'll be right here beside you no matter what happens." When Jack woke up after the surgery, she was true to her word, standing right there with him.

Nearly 20 years later, Jack's ambulance team is called to the scene of a highway accident. A truck has overturned, the driver is pinned in the cab and power tools are necessary to get him out. However, gasoline is dripping onto the driver's clothes, and one spark from the tools could have spelled disaster. The driver is terrified, crying out that he is scared of dying. So, Jack crawls into the cab next to him and says, "Look, don't worry, I'm right here with you; I'm not going anywhere." And Jack was true to his word; he stayed with the man until he was safely removed from the wreckage.

Later the truck driver told Jack, "You were an idiot; you know that the whole thing could have exploded, and we'd have both been burned up!" Jack told him that he felt that he just couldn't leave him.

Many years before, Jack had been treated compassionately by the nurse, and because of that experience, he could now show that same compassion to another. Receiving grace enabled him to give grace. Jesus said, "Now that I, your Lord and Teacher have washed your feet, you should wash one another's feet."
