Fills a gap in one's library
Not many books are written on this theme, yet it is a frequent Biblical theme and is "The Beginning of Wisdom" according to Proverbs.
As one who has preached on the theme and drawn either (mostly) blank gazes or (occasionally) nodding heads, I can testify from personal experience that there are many believers who have no idea whatsoever as to this topic.
Whether it appeals to you or not WE ALL NEED TO READ THIS--for it is a breath of fresh air and a glimpse into eternal reality.
Highly recommended.
