Only conduct yourselves in a manner worthy of the gospel of Christ so that – whether I come and see you or whether I remain absent – I should hear that you are standing firm in one spirit, with one mind, by contending side by side for the faith of the gospel, and by not being intimidated in any way by your opponents. This is a sign of their destruction, but of your salvation – a sign which is from God. For it has been granted to you not only to believe in Christ but also to suffer for him, since you are encountering the same conflict that you saw me face and now hear that I am facing. Therefore, if there is any encouragement in Christ, any comfort provided by love, any fellowship in the Spirit, any affection or mercy, complete my joy and be of the same mind, by having the same love, being united in spirit, and having one purpose.Philippians 1 v 27 – 2 v 2
Alec Motyer does a very good paraphrase of the above verses to challenge us to live a life that is worthy of gospel.
I have a single desire that your daily life should match the worth of the gospel. Without such a life you will never hold your ground against the world, strong in what God has done for you, unanimous, jointly working for your common faith. But such steadfastness has great results: it convicts the world and convinces you; it condemns the world; it confirms the church. Therefore make my joy full by being of the same mind…Alec Motyer The message of Philippians page 101
