- Realizing that the unbeliever is holding back the truth in unrighteousness, the apologist should reject the foolish presuppositions implicit in critical questions and attempt to educate his opponent.
- This involves presenting the facts within the context of the Biblical philosophy of fact:
a. God is the sovereign determiner of possibility and impossibility.
b. A proper reception and understanding of the facts requires submission to the Lordship of Christ.
c. Thus the facts will be significant to the unbeliever only if he has a presuppositional change of mind from darkness to light.
d. Scripture has authority to declare what has happened in history and to interpret it correctly.
3. The unbeliever’s espoused presuppositions should be forcefully attacked, asking whether knowledge is possible, given them:
a. In order to show that God has made foolish the wisdom of the world the believer can place himself on the unbeliever’s position and answer him according to his folly, lest he be wise in his own conceits; that is, demonstrate the outcome of unbelieving thought with its assumptions.
b. The unbeliever’s claims should be reduced to impotence and impossibility by an internal critique of his system; that is, demonstrate the ignorance of unbelief by arguing from the impossibility of anything contrary to Christianity.
4. The apologist should appeal to the unbeliever as the image of God who has God’s clear and inescapable revelation, thus giving him an ineradicable knowledge of God; this knowledge can be exposed by indicating unwitting expressions or by pointing to the “borrowed capital” (un-admitted presuppositions) which can be found in the unbeliever’s position.
5. The apologist should declare the self-evidencing and authoritative truth of God as the precondition of intelligibility and man’s only way of salvation (from all the effects of sin, including ignorance and intellectual vanity):
a. Lest the apologist become like the unbeliever, he should not answer him according to his folly but according to God’s word.
b. The unbeliever can be invited to put himself on the Christian position in order to see that it provides the necessary grounds for intelligible experience and factual knowledge—thereby concluding that it alone is reasonable to hold and the very foundation for proving anything whatsoever.
c. The apologist can also explain that Scripture accounts for the unbeliever’s state of mind (hostility) and the failure of men to acknowledge the necessary truth of God’s revelation; moreover, Scripture provides the only escape from the effects of this hostility and failure (futility and damnation).
