Only let your manner of life be worthy of the gospel of Christ, so that whether I come and see you or am absent, I may hear of you that you are standing firm in one spirit, with one mind striving side by side for the faith of the gospel, (ESV)
In 1976 Francis Schaeffer wrote the book, "How Should We Then Live?" It continues to be a great question. I believe that if one were to have asked the Apostle Paul that question he would have responded with the words we find in Philippians 1:27. "Let your manner of life be worthy of the gospel of Christ."
This high standard of life challenges us to be focused on the Gospel of Christ at all times. It is of far greater significance than anything else that we tend to focus on. The gospel is that good news that Jesus Christ laid aside his eternal glory to condescend and be with the lowliest of all mankind. In order to save them he gave his very life.
It is this very sacrificial nature that is to be the driving force in every believer. At times we tend to forget that having the name Christian means that we bear the very name of Christ. We are his representatives. We are his ambassadors. That means that we ought to act in the same manner towards others that he did. We should be willing to lay down our very lives for the message of the Gospel.
Paul is not sure, in reality, if he will ever see the Philippian believers again. He remains in a Roman prison cell. But, whether he is with them physically or not he wants to hear that they are standing firm for the faith, and are unified. That idea of unity is no small thing. He wants them to be fighting the enemy (Satan) and not fighting one another.
I do not know what you are doing with your life. But, I do know that there is no greater purpose than living in a manner worthy of the Gospel of Christ. Stay focused. Love sacrificially. All for God's glory.
