Discontented people are dangerous people. Those who are unsatisfied in their hearts are prone to actions that might possibly harm themselves or others. Even a cursory glance at the general public reveals a dangerous discontentment. Sometimes the slightest life disruption—or threat of such—results in unwise and unstable reactions. A lack of satisfaction in one’s marriage, family, job, and spiritual life creates vulnerability to temptation. A wise person will stop and consider the level of satisfaction within his or her heart.
