Sun Tzu The Art of War Chapter 3; War by Stratagem

This requires some analysis. War by stratagem is seen in many biblical battles, e.g. Gideon's 300 fighting men with only torches and shofars.



Also, the David and Goliath story meets the criteria for War By Stratagem. The opposing army's general had a very wise stratagem. If he had succeeded, the battle would've been over without a fight.

However, Israel's general baulked this plan, & trumping the Philistine general with a "wild card", i.e. an adolescent boy with a wrist rocket.

How far is too far in life's spiritual war?
When does cunning become deceit?
Where is the line? And, should we look for such a distinction?
