With the United States increasing its attacks on terrorists, the probability of retaliation on U.S. soil is increased. In light of this, what should Americans do?

Understanding our history and understanding the Bible are two good places to start.

During the outset of World War II, the radio news commentator Gabriel Heatter regularly started his program with “There’s good news tonight!” even though U.S. troops were taking a licking. At this difficult time, Franklin D. Roosevelt reminded everyone that “the only thing we have to fear is fear itself,” echoing the words of Christ, “Fear not!” In other words, keep faith and don’t lose your nerve.

Faith generates firmness. It is our primary means for coping with trying times, replacing fear with the confidence and determination needed to overcome paralysis.

Before looking outward for help, we need to look inward and be in possession of ourselves. The Bible and history abound with accounts of men and women whose inner faith gave them the strength necessary to win the day.

A second step we can take is to bolster community spirit. During World War II, neighborhood air raid wardens volunteered as lookouts for possible attacks. People grew victory gardens, metals and old tires were recycled, and rationing stamps were issued. My mother used to say that despite the hardships, it was a romantic time because people sacrificed and worked together.

In the 1800s Alexis de Tocqueville, the French historian best known for his book Democracy in America, studied the principles that made the United States great. He found that citizenship was one of the nation’s pillars of strength.

The predominately immigrant population worked together to move up the social ladder and, more importantly, to make the country better. Neighborhoods abounded in which everyone looked out for each other.

We can’t go back to the past, but from it we can learn that love of our neighbors and country is the best way for pulling together as one. Looking out for others and less for ourselves is essential for overcoming terrorism.

Selflessness, teamwork, faith and respect for God are the very core of our strength. They teach us that if we need to criticize our country, constructive — not destructive — criticism must prevail.

The slogan “In unity there is strength” is found throughout the U.S. Capitol. To beat terrorism, the desire to build up must prevail over a spirit of tearing down.

It is incorrect to think we should leave the battle against terrorism to the military and to increased security efforts. It is true they are needed, but what is equally needed is a strong inner faith, a spirit of sacrifice and solidarity.
