This book investigates the historical and cultural origins of the concepts of heaven and hell within the Christian tradition. Tom Harpur, a former professor of New Testament and a journalist, examines how these afterlife doctrines evolved from ancient mythology and pagan influences rather than strictly biblical foundations. He argues that modern interpretations of these concepts often deviate significantly from the original intent of the early church and the teachings of Jesus. By analyzing historical texts and theological shifts, Harpur provides a critical framework for understanding how these ideas have shaped human morality and fear throughout history.

Readers frequently note the accessible yet provocative nature of Harpur's prose, which challenges long-held dogmatic views. Scholars and theologians often highlight this work as a significant contribution to the conversation regarding the evolution of religious mythology and its enduring influence on contemporary belief systems.
