The idea that Christians are to bring healing into the world—the restoration of people and the reformation of systems that hinder them—seems reasonable enough (in thought, anyway). It is certainly biblical. Reality, however, is another story. The moment one ventures out into the world—either physically or through the lens of the media—you will no doubt be thrown back by the overwhelming suffering, injustice, and evil that frequently seems to rule the day. Islamic terrorists—an enemy with no intelligible goal other than destruction—remind us that evil is real, ruthless, and well-supplied with volunteers. Incomprehensible poverty in India, despotic regimes in the Middle East, and Mexican drug wars us that injustice still reigns throughout much of the world.
