Below is a very helpful done by Trevor Wax with NT Wright. If you don’t know NT Wright is one of the top NT scholars in the world.

I’ve copied the bit that I thought was most important (hope that’s ok).

Trevin Wax: What is at stake in this debate over justification? If one were to adopt Piper’s view instead of yours, what would they be missing?

N.T. Wright: What’s missing is the big, Pauline picture of God’s gospel going out to redeem the whole world, all of creation, with ourselves as part of that.

What’s missing is the big, Pauline view of the church, Jew and Gentile on equal footing, as the sign to the powers of the world that Jesus is Lord and they aren’t.

What’s missing is the key work of the Holy Spirit in enabling the already-justified believers to live with moral energy and will so that they really do ‘please God’ as Paul says again and again (but as Reformed theology is shy of lest it smack of smuggling in works-righteousness again).

What’s missing is an insistence on Scripture itself rather than tradition . . .
