This book is an important part of the historical record of Dr. Norman L. Geisler. It displays Geisler's intellectual gifts and devotion to the Lordship of Christ in his defense of Christianity and classic evangelicalism. This book, written by one of Geisler's long-time and trusted assistants, will be of importance to those who want a first-hand interpretation of Geisler and the significance of Geisler's method for present-day evangelicalism. It provides a clear assessment of the impact of Geisler's embrace of classical realism, classical theism, the doctrine of inerrancy in the context of twentieth century evangelical theology, while providing a way forward to apply Geisler's method in the twenty-first century.
