Impressive! God, Heaven, and Har Magedon, by Meredith Kline, is a must read for any Christian called to a teaching and/or preaching ministry, or for a lay person interested in eschatology. 

Once again, Dr. Kline delivers an impressive exegetical analysis, as he traces the "Mountain of God" typology through the Bible. In this book, he argues that the "Mountain of God" helps illustrate the seen and unseen kingdoms of God, from the Garden of Eden to the final judgment sequences in Daniel, Revelation, and other apocalyptic texts.

This book complements Kingdom Prologue and some of his earlier books which help develop the covenant worldview/theology; it also includes academic papers which he has written.

I think this book will challenge the commonly held (but flawed) apocalyptic/eschatological views of many faithful Christians in the decades to come. In so doing, it will hopefully help enable God's Church to come to a better understanding and fulfillment of its role in this world and the next.
