THE HOLY WAR BY JOHN BUNYAN
John Bunyan wrote another classic besides Pilgrim’s Progress. It was a book called The Holy War. The focus of the story was the capture of a city called Mansoul. In it Diabolus (the devil) has taken it and the battle rages as the Prince Emmanuel works to recapture it. The way it was overcome was because the gates of the city had been compromised. Diabolus and his wicked imps had traversed it by taking advantage of the Eye Gate and Ear Gate which are symbolic of the use of the senses to cause the capture of the city.
