"Be assured," he has been saying, "that by the grace of God, abounding amid trials, it is well with me; and I have very good hope of yet again enjoying this honour, that through my means it may be well with you:--_only_ fix you on this, let this be your concern, to walk as it becomes the gospel: this is the ground on which you must win your victory; this is the line on which alone you can make any effectual contribution to our common welfare, and that of all the Churches." So the Apostle urges. For, let us be assured of it, while we debate with ourselves by what efforts and in what lines we can do some stroke of service to the good cause, or to some special representative of it, after all the greatest and weightiest thing by far that we can do is to be thoroughly consistent and devoted in our own Christian walk, living lives answerable to the gospel. The original suggests that the Apostle thinks of the Philippians as citizens of a state, who are to carry on their life according to the constitution and laws of the state to which they belong. That citizenship of theirs, as we shall afterwards see, is in heaven (ch. iii. 20), where Christ their head is gone. The privilege of belonging to it had reached them through the call of God. And it was their business on the earth to act out the citizenship, to prove the reality of it in their conduct, and to manifest to the world what sort of citizenship it is. Now the standard according to which this is to be done is the gospel of Christ--the gospel, not only as it contains a code of rules for practice, but as it reveals the Saviour to whom we are to be conformed, and discloses a Divine order of holiness and grace to the influence of which our souls are to bow. And indeed, if our thinking, and speaking, and acting held some proportion to the gospel we profess to believe; if they corresponded to the purity, the tenderness, the Divine worth of the gospel; if from step to step of life we were indeed building ourselves on our most holy faith, what manner of persons should we be? This opens more fully in the next chapter.
