Here is a selection of books I recommend on social justice.
Top Recommendation

Confronting Injustice without Compromising Truth
Early in the publication process I was asked to read the manuscript and consider writing an endorsement. Once I read it, I was glad to do so. I’ll leave that blurb as my conclusion: Confronting Injustice without Compromising Truth is the book I’ve been waiting for! This is the book that explains and analyzes the social justice movement—that treats it fairly and evaluates it critically. This is the book that prioritizes the gospel as the foundation for any true justice. This is the book that helps Christians understand why they must emphasize social justice, but why they must emphasize the right kind of social justice. This is the book I highly recommend.
Other Recommendations

The Rise and Triumph of the Modern Self
This book deserves the praise and commendations it received. It’s truly a fascinating read. (See also the briefer Strange New World.)

Why Social Justice Is Not Biblical Justice
The strength of this book is not just in calling people away from unbiblical notions of justice, but in calling people toward a fully-formed worldview in which Christians care more for justice—true justice—than anyone else.

This one goes a little beyond social justice in general and focuses on its application to the criminal justice system.

It’s important to note that this book is not written by Christians but, in fact, by antagonists to the Faith. Yet that adds an interesting element to it.

Written for a broad audience, updated to reflect current realities, and practical about how Christians can respond in the home, the church, the office, and the classroom.

On the many and often less obvious ways that abortion brings harm—and how deeply society has been impacted by its acceptance and celebration.
