I found this to be an amazing book--the very first chapter got me hooked--"The Vandalism of Shalom". Takes time to define sin in a way that is both approachable and accountable. It is so much easier if we work at it from a perspective that when we sin we lose what is precious and cherished. Lot's of folks end up feeling like the are cheated and miss all the fun if they have to do what is right. This book helps us see what we end up losing when we don't choose the path of righteousness.
