The exhortation is enforced by pointing to others who had gone far astray, and of whom he had warned the Philippians often, possibly by letter. Who these unworthy disciples were remains obscure. They were clearly not the Judaisers branded in verse 2, who were teachers seeking to draw away the Philippians, while these others seem to have been 'enemies of the Cross of Christ,' not by open hostility nor by theoretical errors, but by practical worldliness, and that in these ways; they make sense their God, they are proud of what is really their disgrace, namely, they are shaking off the restraints of morality; and, most black though it may seem least so, they 'mind earthly things' on which thought, feeling, and interest are concentrated. Let us lay to heart the lesson that such direction of the current of a life to the things of earth makes men 'enemies of the Cross of Christ,' whatever their professions, and will surely make their end perdition, whatever their apparent prosperity. Paul's life seemed loss and was gain; these men's lives seemed gain and was loss. From this dark picture charged with gloom, and in one corner showing white waves breaking far out against an inky sky, and a vessel with torn sails driving on the rocks, the Apostle turns with relief to the brighter words in which he sets forth the true affinities and hopes of a Christian. They all stand or fall with the belief in the Resurrection of Christ and His present life in His glorified corporeal manhood. I. Our true metropolis. The Revised Version puts in the margin as an alternative rendering for 'citizenship' commonwealth, and there appears to be a renewed allusion here to the fact already noted that Philippi was a 'colony,' and that its inhabitants were Roman citizens. Paul uses a very emphatic word for 'is' here which it is difficult to reproduce in English, but which suggests essential reality. The reason why that heavenly citizenship is ours in no mere play of the imagination but in most solid substance, is because He is there for whom we look. Where Christ is, is our Mother-country, our Fatherland, according to His own promise, 'I go to prepare a place for you.' His being there draws our thoughts and sets our affections on Heaven. II. The colonists looking for the King.
