I just finished reading Counted Righteous in Christ by John Piper (2002, Crossway Books).
In this book, Piper addresses the doctrine of imputation of Christ's righteousness (i.e. passive
and
active obedience), which apparently has been questioned in some modern theological dialogue. Unlike some of his other books that I read before (e.g., Desiring God, Pleasures of God), this book was not as easy to read due to the technical nature of the discussion. Piper uses lots of Greek, refers to other commentaries, and has many lengthy (but helpful) footnotes. In addition, he is primary interacting with and critiquing another theologian named Robert Gundry whose work I was not aware of, so there was no compelling reason for me to labor through this book.
However, I am glad that I did, because I found this book very good and helpful. I am certainly not as widely read as I should be on this very important topic, but what I found to be very refreshing about this book is that it is thoroughly exegetical. A major portion of the book is devoted to wrestling with what the Bible texts has to say on this topic. Unlike a few other books that I read that mainly addresses the issue from a systematic point of view (which is no doubt also helpful), I appreciate how Piper guides the reader to engage with Scripture itself and derive our theology based on what the text says. Of course, those of opposing view would also claim that their reading of Scripture is either just as correct or more correct. As somebody else said somewhere else, however, I do think that there is such a thing as honest exegesis, and I believe Piper does provide us with an excellent one (or, at least more honest than those he is challenging).
I would recommend this book to anyone interested in the topic. I especially would recommend reading Piper's treatment of Romans 5 in this book. In closing, I leave with you a question that Piper poses himself in the onset of the book:
"Why would a pressured pastor with a family to care for, a flock to shepherd, weekly messages to prepare, a personal concern for wayward children, a love for biblical counseling, a burden for racial justice, a commitment to see abortion become unthinkable, a zeal for world evangelization, a focus on local church planting, and a life-goal of spreading a passion for the supremacy of God in all things for the joy of all peoples through Jesus Christ devote so much time and energy to the controversy over the imputation of Christ's righteousness? And why should schoolteachers, engineers, accountants, firemen, computer programmers, and homemakers take the time to work through a books like this?"
And to paraphrase his answer, because much is at stake, including my marriage, my [future] children, and the glory of Christ.
