So in presenting apologetic arguments for some conclusion, we want to raise the price of denying the conclusion as high as we can. We want to help the unbeliever see what it will cost him intellectually to resist the conclusion. Even if he is willing to pay that price, he may at least come to see why we are not obliged to pay it, and so he may quit ridiculing Christians for being irrational or having no reasons for what we believe. And if he’s not willing to pay the price, then he may change his mind and come to accept the conclusion we’re arguing for.
