Sam Childers, is better known as the Machine Gun Preacher.
Childers life is the basis of a movie starring Gerard Butler. It centres around his transition from a drug-dealing biker to a man who found God and turned his focus to rescuing kids in some of Africa's most dangerous areas.
Sam believes that whoever hears his story will have hope for their life, "If they just take a little bit of that story in,” he said. “Just look deep into my story, if God can change me and use me... Imagine what he can do for you."
