John Piper's Concern in the Justification Debate

Piper on imputation: John Piper's Concern in the Justification Debate :: Desiring God:

So I'm giving this little video clip just to say that I really believe that Christians have to be loving, they have to be just, they have to be caring. In other words, the fruits of the Spirit really matter. We are not born again if we are not living differently than we would if we weren't born again. I just want to say that the doctrine of justification by faith alone, or imputation through union with Christ along the instrument of faith alone, is the best way forward in that.
