Some have taken the time to analyze their presuppositions. Most have not. But each non-regenerate person is caught in the horns of a dilemma because it is impossible to be consistent in logic or practice. This holds true along the whole spectrum of people.
Christian Apologetics: Two Purposes
Francis Schaeffer’s holds a rather basic view concerning apologetics. He explains there are two purposes of Christian apologetics. “The first is defense. The second is to communicate Christianity in a way that any given generation can understand” (The God Who Is There, 151).
Schaeffer begins his approach to apologetics by pointing out that every non-regenerate person enters the discussion with a set of presuppositions. Some have taken the time to analyze their presuppositions. Most have not. But each non-regenerate person is caught in the horns of a dilemma because it is impossible to be consistent in logic or practice. This holds true along the whole spectrum of people. Every person whether a University student, housewife, businessman or disgruntled teenager is stuck and boxed in by the logic of his or her presuppositions. Thus, Schaeffer writes, “You are facing a man in tension, and it is this tension which works on your behalf as you speak to him . . . A man may try to bury the tension and you may have to help him find it, but somewhere there is a point of inconsistency” (The God Who Is There, 133). Schaeffer adds, “To have to choose between one consistency or the other is a real damnation for man. The more logical a man who holds a non-Christian position is to his own presuppositions, the further he is from the real world; and the nearer he is to the real world, the more illogical he is to his presuppositions” (The God Who Is There, 133-134).
Therefore, the place to begin in the real world with real people is to find out where the tension exists. Once the point of tension is uncovered the apologist must push the non-regenerate man toward the logical conclusion of his presuppositions. Schaeffer warns, “Pushing him towards the logic of his presuppositions is going to cause him pain; therefore, I must not push any further than I need to” (The God Who Is There, 139).
Schaeffer calls this approach “taking the roof off” because every man has constructed a roof over his head to protect himself at the point of tension. “At the point of tension the person is not in a place of consistency in his system, and the roof is built as a protection against the blows of the real world, both internal and external” (The God Who Is There, 140).
