This book is more a book on epistemology than apologetics. Since the author is a strict Calvinist, he has a tendency to merge apologetics and evangelism, since the only result of either is not much, since the hearer can come to Christ only if the Holy Spirit renews his or her heart. The author denies any real efficacy to apologetics, either expressly or implicitly. Also the author does not seem to realize that apologetics can also be useful for believers and to contradict scoffers. As such, epistemological purity may not be a requisite. For example, as a believer, it might be comforting to me to know that historical evidences support (but do not "prove") the ressurection of Jesus. The Holy Spirit, in confirming the Bible as the true Word of God, never confirms that which is contrary to what we see in the created order, especially after the partial reversal of the noetic effects of sin.
The author does make an interesting insight in commenting on another apologist, wherein he asserts that that the other apologist ascribes to reason or natural theology that which was most likely brought to the mind of the apologist by the Holy Spirit after conversion. In other words, once our minds and hearts are renewed by the Holy Spirit, we cannot "unthink" or "unknow" the things revealed by the Spirit, and in trying to think through was the natural man may know or discover, acribe to fallen man things which are only revealed to the redeemed. This of course applies to all truly redeemed interpreters, and makes it more difficult to draw the line between what is know by fallen reason and conscience (perhaps also natural law) and the mind enlightened by the Spirit.
The book is worth reading, but not if you are looking for useful insights into practical apologetics. If epistemology is your interest, then the book should be of some use.
