When I call this book a "difficult and inspiring read," it's not because of the prose. The book is written in a matter-of-fact, conversational way and it flows well.No, the difficult part is the subject matter. Sam Childers pulls no punches about his past as a drug-dealer, a biker hoodlum, etc. He takes the same approach to his work as a Christian soldier fighting against the LRA in Southern Sudan, rescuing children abused and orphaned by the vicious militia.Make no mistake, this is a violent tale ... in a violent place. Childers starts out helping roof a building for charity and winds up establishing an orphanage right int he middle of a war zone. He talks about his walk with God, his inspiration ... and the desperate need for funds.This book was the inspiration for an equally difficult and inspiring film, "Machine Gun Preacher." Both are highly recommended.
