There is a difference between physical and moral courage. If you earn a black belt in karate, you may be called upon to be physically courageous but such events will be extraordinary. Even police officers, fireman and military personnel may only have to be physically courageous a few times in their careers.
Moral courage is needed more often than physical courage. Moral courage may mean the challenge to stay with a belief when your position may not be the most popular. Moral courage can be standing tall against bigotry, prejudice, unfairness, and bullying behavior. Moral courage is a challenge to do what is right, regardless of the personal consequences. Moral courage may ask you to forgive.
Think of people in physical or mental anguish. You may see courage being lived every day.
