Growing Your Faith (2004) by Jerry Bridges is a useful volume about the process of progressive sanctification that distills much of Bridge's previous work. I have often said that Jerry Bridges is one of my favorite writers and this book provides further support. If you have never read anything by Bridges, this may be a good place to start. Growing Your Faith includes sections from several of his previous books all around the central theme of Christian growth. Like his previous works, his ability to ground growth in grace is exceptionally strong. This book also included a few new chapters, including one on getting into the word of God, which was really well done.
If you are familiar with Brdiges previous work, you may wish to skip this one, but if you are hoping to get a flavor for a humble, readable gospel-centered man, this would be a great place to start.
