In an interview with Trevin Wax in the Context of speaking of Piper’s The Future of Justification: A Response to N. T. Wright Tom Wright states the following,
I would prefer that [Piper] exegete Paul differently, of course, but the people I really want to fight are (like for Paul) the pagans out on the street who are reordering society in ways that are deeply dehumanizing. The gospel is for the pagans.
Now most Evangelicals would agree with this sentiment. But not Paul, I believe.
In Titus 2:11-14 Paul states,
For the grace of God has appeared, bringing salvation for all people, training us to renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in the present age, waiting for our blessed hope, the appearing of the glory of our great God and Savior Jesus Christ, who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works.
Paul emphatically contends that the Grace of God, the Gospel, is bringing salvation for all people (including the Pagan); and at the same time is training us (the Christian) to live self-controlled, upright, and godly lives now as we wait for our blessed hope, the second coming of Christ.
Thus, the same Gospel that justifies (not the way Tom Wright contends) also sanctifies. If we as Christians desire to become “mature manhood, to the measure of the stature of the fullness of Christ” (Eph. 4:13), we must be like Paul and be “eager to preach the gospel to you [the Christian] also who are in Rome” (Romans 1:15).
Now to him who is able to strengthen you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery that was kept secret for long ages (Romans 16:25)
