This book releases at the end of the month, but it’s already available for free as a PDF:
John Piper and David Mathis, eds. Acting the Miracle: God’s Work and Ours in the Mystery of Sanctification. Wheaton: Crossway, 2013.
This book is theologically informed and pastorally wise. It helpfully distinguishes and defines definitive and progressive sanctification, and it shrewdly shows how to approach Christian living without being reductionistic.
My favorites chapters are the ones by Mathis, Piper, and DeYoung.
