The Art of War is considered by many to be the seminal work on war tactics and strategies. Attributed to Sun Tzu, a sixth century BC military commander, this ancient Chinese military treatise divides the various aspects of warfare into thirteen chapters: Laying Plans, Waging War, Tactical Dispositions, The Nine Battlegrounds, and the Use of Spies among others.
Beyond the obvious military applications of Sun Tzu’s wisdom, his principles have implications for other disciplines. I don’t think it’s a stretch, for example, to apply his lectures on how to win at war to the Christian who desires to overcome his battles in the spiritual realm with the devil.
