It is so interesting. Where I read to you in the first line of verse 27, "Whatever happens make sure that your everyday. . ." That is the way it is translated in the Phillips Bible. In the New King James this word "everyday" is translated "conduct." I believe in the King James the word might be "conversation." Do you know what the word is there in Greek? The word in Greek is the same word from which we get the English word "politics."
What is Paul talking about here? This word can also be used in the sense of citizenship. He is drawing here on what he is saying about our responsibility. We are to conduct our everyday life according to what would be expected of a citizen—not a citizen of Philippi though, but a citizen of the Kingdom of God.
Is there any doubt what we need to be doing here? We are spiritual soldiers and we are to be of one mind, and unified. In these verses it hit me that Paul is really pouring out his heart to us, to stand fast. Because this war, again, it is not just physical but is also mental. And this life that we have is not easy. And maybe that is why Paul uses such strong language in here.
