It may be asked how this should be, if the Philippians were genuine and hearty Christians, such as the Apostle's commendations bespeak them? Here a principle comes to light which deserves to be considered. Even those who have cordially embraced Christianity, and who have loyally given effect to it in some of its outstanding applications, are wonderfully prone to stop short. They do not perceive, or they do not care to realise, the bearing of the same principles, which they have already embraced, upon whole regions of human life and human character; they do not seriously lay to heart the duties Christianity imposes or the faults it rebukes in those departments. They are pleased to have won so much ground, and do not think about the Canaanites that still hold _their_ ground. So, in whole regions of life, the carnal mind is allowed to work on, undetected and practically unopposed. This tendency is aided by the facility we have in disguising from ourselves the true character of dispositions and actions, when these do not quite plainly affront Christian rules. Self-assertion and bad temper, for example, can put on the character of honest firmness and hearty zeal. More particularly, when religious principles have led us into certain lines of action, we are apt to take for granted that all is right we do in those lines. Religious zeal leads a man to take trouble and incur responsibility in Church work. Under this notion, then, he readily persuades himself that all his Church work is conscientious and disinterested: yet it may be largely and deeply tainted with the impulses of the fleshly mind. In a measure it might be so here. The Philippians might be generally a company of sincerely Christian people. And yet the churchmanship of some of them might disclose sad tokens of selfishness and bitterness. Therefore they must be called to give heed to the principles and to give effect to the motives that expel those sins. In all this we may feel ourselves in the region of commonplaces; we know it all so well. But the very point in hand is that for the Apostle these are not commonplaces. He is greatly in earnest about the matter, and his heart is full of it. We do not understand him until we begin to sympathise with his sorrow and his anxiety. This is for him no mere matter of expediencies or of appearances. He is striving for the victory of grace in the souls of his beloved friends; for the glory of Christ; for his own comfort and success as Christ's minister. All these are, as it were, at stake upon this question of the life of the Philippian Church proving to be, under the influence of Christ, lowly, loving, and answerable to the gospel.
