Book excerpt: This is a book about spiritual formation, the "grace-driven developmental process in which the soul grows in conformity to the image of Christ." The acid test of all spiritual formation is this: Are you becoming more like Jesus? Are the contours of your character being shaped by his image, formed in his likeness? This ongoing transformation is possible for you. You can become more and more like Jesus Christ. But there is only one way: through your increasing understanding and application of the gospel. That's what this book is about. Book jacket.
