Crossway Books has re-released Tim Chester's book, You Can Change: God's Transforming Power for our Sinful Behavior and Negative Emotions. It had originally been published by IVP in England.
I recently read this book and found it to be one of the best, concise books I've read on how change happens in the lives of God's people for His glory. It is full of sound principles and helpful illustrations.
If you're looking for a good book on the basics of the nature of biblical change, this is it.
