Presuppositional Apologetics

In defending the Christian faith, the most important question before us is "What sort of defense will best glorify our God (cf. 1 Cor. 10:31)?"� God forbid that in seeking to defend the faith before others we should in that very act compromise it. The so-called "presuppositional"� school of apologetics is concerned above all with answering this question. Among all the sources of divine revelation (including nature, history, human beings in God's image), Scripture plays a central role. Indeed, though the point cannot be argued in detail here, my view is that Scripture is the supremely authoritative, inerrant Word of God, the divinely authored, written constitution of the church of Jesus Christ. Scripture is therefore the foundational authority for all of human life including apologetics. As the ultimate authority, the very Word of God, it provides the foundational justifications for all our reasoning, without itself being subject to prior justification.
