“First, everyone has presuppositions—basic beliefs that we take for granted before we begin to draw conclusions about the universe. These include things like laws of logic and the reliability of our senses. All of our presuppositions taken together form our worldview. Our worldview determines how we interpret the facts, and even what constitutes a "fact." Most people are not aware that they have a worldview, and consequently have not given much thought to it. Second, the presuppositions of the unbeliever do not comport; they don't "go well together." They are inconsistent, often self-refuting, and would make knowledge impossible. The unbeliever's worldview cannot account for the preconditions of intelligibility—those things that are required in order for us to know anything. Preconditions of intelligibility include things like laws of logic, uniformity of nature, and absolute morality. Without a rational basis for the preconditions of intelligibility, the unbeliever cannot really know anything by his own worldview. He can certainly believe things, but he has no way to prove them, and thus he doesn't actually know them, based on his own worldview. Third, unbelievers cannot consistently act upon their own professed worldview. If they did, they couldn't know anything; they wouldn't be able to function at all. Their own presuppositions cannot make sense of the universe. Therefore, unbelievers will compulsively "steal" Christian presuppositions in order to function. They are "presuppositional kleptomaniacs," constantly assuming things (like laws of logic) that make no sense upon their professed unbiblical worldview. The fact that unbelievers consistently fail to embrace their own presuppositions shows that in their heart of hearts, they really do know the biblical God. Fourth, to expose the inconsistency in unbelieving thought, we should use the "don't answer, answer" strategy. That is, we never embrace the presuppositions of the unbeliever; otherwise, we, too, will draw the wrong conclusions about the evidence and will be reduced to foolishness. However, we do show for the sake of argument where the non-biblical assumptions of the unbeliever would lead if they were true. We show that the unbeliever cannot make sense of anything as judged by his own standards. We are exposing the fact that the unbeliever does know the biblical God but has suppressed that truth in unrighteousness (Rom. 1: 18). We expose the foolishness of the unbeliever with an attitude of reverence and humility, remembering that the unbeliever is also made in the image of God (Gen. 1: 26–27), and is to be treated with respect.”
