I've read the book far too quickly to give an adequate introduction so I'll just post his overview of one of my favouriate chapters: "Biblical Ontology and Ecclesiology" (doesn't that title just send a shiver down your spine?).
These apostolic and prophetic attitudes toward time become the central concern in the fourth chapter, where I analyze the challenges presented to the historian by specific texts in the book of Revelation. The category of history does not appear in these texts and it becomes quite misleading when the texts are forced into conformity to the modern category. By contrast the category of the heavens, so absent from modern historical discussion, is assumed to be the ultimate reality. Historians are primarily concerned with placing all events within earthly time and the temporal process; biblical writers are essentially concerned with the eternal purposes and time-transcending activity of the creator of the heavens and the earth. Moreover, in sharp contrast to modern thought, which tends to reduce the heavens and the earth to spatial measurement, biblical writers assume the basic and continual interpenetration of the two realms, with the heavens providing the creative source, the daily sustenance, and the final goal of everything earthly. Because the categories of space and time are no longer of use in measuring heavenly realities, biblical thought makes dubious the modern scholar's reliance on those categories (23).
