Nothing more appropriate in a letter that deals with the essence of faith than to end with a doxology, an exclamation of praise, which is dense with content and full of key terms and phrases which were dealt with throughout the work:
Now to him who is able to strengthen you according to my gospel and the proclamation of Jesus Christ, according to the revelation of the mystery that had been kept secret for long ages, but now is disclosed, and through the prophetic scriptures has been made known to all the nations, according to the command of the eternal God, to bring about the obedience of faith — to the only wise God, through Jesus Christ, be glory forever! Amen.
Romans 16:25-27 NET
Paul ends with a phrase that he had written at the beginning of the letter, giving us an idea of its content: “the obedience of faith.” The placing of this phrase is called an inclusio.
In chapter 3, the NVI (the Brazilian rendering of the NIV) translates the Greek term for “work(s)” as “obedience,” thereby confusing the message of the letter.
In a Bible version otherwise trustworthy and commendable, the NVI shows the evangelicals’ blind spot, which makes them lose the nature of the correct response to the message — obedience. Since Martin Luther, they have clung to the doctrine of “faith only,” affirming that one can do nothing for one’s salvation.
In his letter, Paul insists on the necessity of obedience for salvation. Read, for example, Romans 6:17-18. And in this double mention of “obedience of faith,” he declares what he hopes to promote in his hearers when he preaches the gospel.
This is also our message and our hope.
