"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, and not frightened in anything by your opponents. This is a clear sign to them of their destruction, but of your salvation, and that from God. For it has been granted to you that for the sake of Christ you should not only believe in him but also suffer for his sake, engaged in the same conflict that you saw I had and now hear that I still have."

I) Live worthy of the gospel of Christ by standing unified in Him. (Verses 27-28)
(Philippians 2:1-10, 14-18, 3:20, 4:1; Ephesians 6:10-20)

“THE word “conversation” does not merely mean our talk and converse one with another, but the whole course of our life and behaviour in the world. The Greek word signifies the actions and the privileges of citizenship, and we are to let our whole citizenship, our actions as citizens of the new Jerusalem, be such as becometh the gospel of Christ.” Charles Spurgeon

“Now, how does a citizen of heaven conduct himself? Follow verse 27, "in a manner worthy of the gospel of Christ" - consistent with what we know, consistent with what we teach, consistent with what we preach, consistent with what we believe. That is integrity. That is integrity. You see, the thing that is stripping the church today of all of its credibility is that it says one thing and does another thing, that it lives one way and preaches another way. It is only when the church lives true to its message, and by the church I mean you and me. It is only when it's embodying in its behavior, its beliefs that it has integrity. And only when it has integrity is the message clear and believable. The greatest weapon the church has is its integrity. And when the church does not conduct itself “in a manner worthy of the gospel of Christ,” it cuts itself up in terms of its ability to be a whole person representing the body and person of Christ.” John MacArthur

II) Live worthy of the gospel of Christ by rejoicing in the grace of suffering for Him. (Verses 29-30)
(2 Timothy 3:12; John 15:18-25)

“Indeed, if you understand Christ you understand the gospel. Christ is the author of it; he, in the council chamber of eternity proposed to become the surety for poor fallen man;' he, in the fulness of time, wrought out eternal redemption for as many as his Father had given him. He is the author of it as its architect and as its builder. We see in Christ Jesus the Alpha and the Omega of the gospel. He has provided in the treasury of grace all that is necessary to make the gospel the gospel of our salvation. And as he is the author of it, so he is the matter of it. It is impossible to preach the gospel without preaching the person, the work, the offices, the character of Christ. If Christ be preached the gospel is promulgated, and if Christ be put in the background, then there is no gospel declared.” Charles Spurgeon
