Historically, Protestants have believed that the moment a person placed his or her faith in Jesus Christ (as the God-man who lived and died as a substitute for sinners), that individual received the righteousness of Jesus Christ. This righteousness is “imputed” or transferred to their account. From then on, God looks upon the person as possessing the very righteousness of Jesus Christ. N.T. Wright has joined others in making light of this notion with quips such as “… it makes no sense that the judge [God] imputes, imparts, bequeaths, conveys or otherwise transfers his righteousness to either the plaintiff or the defendant. Righteousness is not an object, a substance or gas that can be passed across the courtroom.” This book is Pastor Piper’s response. What’s at stake? The basis of our acceptance before God. Do the good works performed by believers through the aid of the Holy Spirit in some way contribute to (or secure) our right standing with God, or are they the evidence that we already have a right standing with God? Among other things, this has implications for a believer’s assurance of salvation.
