People who have known only happiness and are suddenly confronted with grave difficulties sometimes are so at a loss to know what to do that they aggravate their condition. The meaning of strife must be remembered even in times of peace. In other words, one must not give in to hard times. One must be trained in faith and in physical strength to remain stable no matter what conditions are encountered. Each new unpleasant experience resolutely faced will further strengthen faith and make it all the more unshakable.

The truth of this statement applies not only to individual human beings but to groups and nations as well. Stimulation is important. Like stagnant water, a person who lives in constant security becomes complacent and, figuratively, goes stale. Flowing water stays bright and clear because of the many obstacles it encounters. In a similar way, a human being who is frequently stimulated to find ways to solve new difficulties grows gradually stronger. (Page 134)
