This book is about decisions. Not the everyday kind such as "What should I wear today?" or "Where shall we eat tonight?" but decisions dealing with life, death, and protecting the innocent. Self defense concerns decisions of survival for the individual. It can also decide the fate of a nation and its citizens.
If you ever question yourself about your God given rights to self defense, or wonder what scripture says about the matter, this is a great book to read. Greg does a good job of laying everything out. This book contains a lot of scripture and a good amount of cases and examples of situations where use of deadly is and is not permissible.
