This book is Van Til's most complete succinct introduction to his method of defending the faith. Here he presents the underpinnings of this uniquely biblical approach. Van Til shows how Christian apologetics is rooted in a unified system of scriptural truth, a worldview that encompasses all spheres of knowledge. Noting the ultimate conflict between Christian and non-Christian systems, Van Til sets forth a method of argument that centers on an all-important, biblically defined point of contact with the unbeliever. In this second edition William Edgar, a leading proponent of pre-suppositional apologetics, provides a new introduction and explanatory notes throughout the text.
