D.A. Carson says,
I cannot too strongly celebrate the publication of this book. Owing in part to several decades of dispute over justification and how a person is set right with God, we have tended to neglect another component of conversion no less important. Conversion under the terms of the new covenant is more than a matter of position and status in Christ, though never less: it includes miraculous Spirit-given transformation, something immeasurably beyond mere human resolution. It is new birth; it makes us new creatures; it demonstrates that the gospel is the power of God unto salvation. All the creedal orthodoxy in the world cannot replace it. The reason why ‘You must be born again’ is so important is that you must be born again."
