I first read this book many years ago, in an earlier edition. Now it's been totally rewritten for a new generation. And, boy, does our generation need it! It's to the absolute shame of Christians that so many crucial issues have been faced head-on by those of other (or no) faiths, while Christians maintain the silence of happy ignorance and profit from the oppression of the poor.
If you're like most of us, you could go to your kitchen or look at the logos on your clothing, and you'd quite possibly find that you've been adding to the profits of a company that oppresses people who are already poorer than we in the West can imagine. *WE* are the bad guys. *WE* are guilty of the crimes the Old Testament prophets protested about.
"You that trample on the needy, and bring to ruin the poor of the land... buying the poor for silver and the needy for a pair of sandals." (Amos)
As Christians, we need to repent not only our individual sins, but the sins of the society to which we belong.
This book points out many (not all) of the issues, but more importantly, suggests some ways we can begin to put our faith into practice by addressing those issues.
