English Standard Version (ESV)
It's tough to figure out just how to live in society as a Christian. Paul is trying to advise these new Christians on their role, and he avoids telling them to throw off the shackles of the Roman empire altogether. They need to be responsible citizens, not seeking to overthrow Rome by resistance in a day, but rather starting a movement based on the selfless love of Christ that would overtake the world.
I'd argue we're still a part of that movement, trying to figure out how to be responsible citizens while still living according to the love of Christ. It isn't easy, and there are tough questions we have to wrestle with, but we are called to follow Christ while participating in society, helping reform it while being part of it.
