In Defense of the Eschaton is an anthology of William D. Dennison's essays on the Reformed apologetics of Cornelius Van Til. Written over the course of Dennison's many years of study, the chapters in this volume investigate Van Til's theory of knowledge, revelation, common grace, antithesis, Christian education, and the history of ideas, as well as examine key Scriptures to identify the redemptive-historical structure of a biblical apologetic method.
In the end, Dennison finds that Reformed apologetics must take eschatology seriously. According to the New Testament, the believer has been transferred by faith in Christ into the final stage of history. As a citizen of heaven, the Christian apologist must defend the eschaton of the age to come against the satanic attacks of this present world.
