Is anything more obvious than the presence of evil in the universe? its nagging, prehensile tentacles project into every level of human existence. We may debate the origin of evil, but only a victim of superficial optimism would debate its reality. Evil is stark, grim, and colossally real.
Within the wide arena of everyday life we see evil in all of its ugly dimensions. We see it expressed in tragic lust and inordinate selfishness. We see it in high places where men are willing to sacrifice truth on the altars of their self-interest. We set it in imperialistic nations crushing other people with the battering rams of social injustice. We see it clothed in the garments of calamitous wars which leave men and nations morally and physically bankrupt.
In a sense, the history of man is the story of the struggle between good and evil. All of the great religions have recognized a tension at the very core of the universe. Hinduism, for instance, calls this tension a conflict between illusion and reality; Zoroastrianism, a conflict between god of light and the god of darkness; and traditional Judaism and Christianity, a conflict between God and Satan. Each realizes that in the midst of the upward thrust of goodness there is the downward pull of evil.
Christianity clearly affirms that in the long struggle between good and evil, good eventually will emerge as victor. Evil is ultimately doomed by the powerful, inexorable forces of good. Good Friday must give way to the triumphant music of Easter. Degrading tares choke the sprouting necks of growing wheat for a season, but when the harvest is gleaned the evil tares will be separated from the good wheat. Caesar occupied a palace and Christ a cross, but the same Christ so split history into A.D. and B.C. that even the reign of Caesar was subsequently dated by his name. Long ago biblical religion recognized what William Cullen Bryant affirmed, "Truth crushed to earth will rise again," and what Thomas Carlyle wrote, "No lie you can speak or act but it will come, after longer or shorter circulation, like a bill drawn on Nature's Reality, and be presented there for payment—with the answer, No effects."
