Paul K. Jewett: The Axioms of Reason Versus The Axiom of Scripture

The axioms of reason are non-demonstrable assumptions. Why should faith not be granted the same privilege? The denial of the truths of faith is, in the last analysis, no less a faith than faith itself, for it rests on personal assumptions which are apart from scientific necessity. In other words, as the truth of reason carries its own evidence, so also with faith. To the mind to whom the axioms of reason are not self-evident, they cannot be proven. So also in the case of faith: for the mind that is not enlightened by faith, the evidence of faith is ridiculous. But for the man whose eyes have been enlightened by the Spirit, faith has its proper evidence, though different from that of reason. The only sufficient ground of faith is the authority of God Himself as he addresses me in His Word.  -- Paul K. Jewett, Emil Brunner's Concept of Revelation
