This is a good introductory book on the issue of Christians working with the poor. There is a lot of theology and theory.
I recommend it to any Christian leader who is not already working with the poor, or who wonders if he/she should continue working with the poor. Tim Keller makes very good arguments how Christians are commanded to work with the poor. This kind of work isn’t just for a select group of Christians, it’s for all.
If you are already working with the poor and you don’t need any more convincing and you’re hoping to find some practical advice on how to do the work you won’t find much of that in this book. There is a chapter on how to do the work but it is very general.
Overall it is an interesting book and delivers some strong arguments. If you already listen to much of Tim Keller’s preaching you will find this book is a summary of the message that threads through so much of his preaching.
