The Invisible War, by Donald Grey Barnhouse and published by Classics.
This book is an exploration of the great conflict going on between good and evil within the spiritual realm, Dr. Barnhouse carefully traces this vast spiritual conflict back to the period before the beginning of recorded time. Step by step, he then follows its unfolding to the final battle at the end of time. Here are answers to questions that have long troubled thinking people – concerning the trials, sufferings, and difficulties of life – with added helpful suggestions for facing life’s obstacles.
Dr. H H Ehrenstein says, “I am certain that this book will take its place as one of the greatest Dr. Barnhouse wrote during his lifetime, unfolding as it does an entirely new area of biblical truth for many readers who have never before contemplated this invisible battle involving God, Satan, angels, demons, and mankind. Indeed, I know of no other available book of so complex a subject.”
