Today, I ran across a soul-stirring treatment of Romans 1:5 by John Stott.
"through whom we have received grace and apostleship to bring about the obedience of faith among all the Gentiles for His name's sake"
"We should be 'jealous' (as Scripture sometimes puts it) for the honour of his name - troubled when it remains unknown, hurt when it is ignored, indignant when it is blasphemed, and all the time anxious and determined that it shall be given the honour and glory which are due to it. The highest of all missionary motives is neither obedience to the Great Commission (important as that is), nor love for sinners who are alienated and perishing (strong as that incetive is, especially when we contemplate the wrath of God, verse 18), but rather zeal - burning and passionate zeal - for the glory of Jesus Christ" (John R.W. Stott, The Message of Romans)
