I wanted to share this with you. I read this just this morning in the Preface to N.T. Wright’s Justification: God’s Plan and Paul’s Vision and thought it was excellent.
“Second, the question is about the means of salvation, how it is accomplished. Here John Piper, and the tradition he represents, have said that salvation is accomplished by the sovereign grace of God, operating through the death of Jesus Christ in our place and on our behalf, and appropriated through faith alone. Absolutely. I agree a hundred percent. There is not one syllable of that summary that I would complain about. But there is something missing—or rather, someone mission. Where is the Holy Spirit? In some of the great Reformed theologians, not least John Calvin himself, the work of the Spirit is every bit as important as the work of the Son. But you can’t simply add the Spirit on at the end of the equation and hope it will still have the the same shape.”
