(Otherwise called The Kingdom of God versus the Kingdom of Heaven) This book is a Christian political history, or a Christian philosophy of history. It draws the line between the Kingdom of God and the Kingdom of Heaven, and proves conclusively that they are different and never have been (nor ever will be) the same. The origin, development, history, and consummation of both Kingdoms are given, and then secular history is placed alongside for an enlightening comparison. 298 pages. Author: Dr. Peter S. Ruckman.
