Philippians 4:9

Those things which ye have both learned, and received, and heard, and seen in me, do; and the God of peace shall be with you,

In order that peace and joy may remain within the Christian hearts and within the Christian congregations, it is necessary that Christians avoid all things which might disturb such harmony in the Spirit. Their thoughts must be directed solely to things that are well-pleasing to God. That is evidence of true progress in sanctification, to seek what pleases God and is of benefit to one's neighbor. The apostle enumerates the virtues which the believers must keep in mind, upon which they should think Their minds should be engaged with matters which are true, truthful, truth-speaking, sincere, frank, and open, especially toward God who searches hearts and minds; with things which are honest or honorable, belonging to and fitting true Christian dignity, since the Christians must never forget what they owe to their station as children of God in the world; with matters which are just and right, which agree with all just expectations of men, which are in accord with the Law. The believers should reflect carefully also upon things which are pure, chaste, clean in words and deeds, never become guilty of lascivious allusions or of filthy deeds; upon things which are lovely, well-pleasing, not only omitting all vain and empty conversation, but, above all, offensive garrulity; upon things of good report, which reflect credit upon the Christian religion and do not cause people to place Christian conversation on a level with that of the world. All such things the Christians will choose as the subject of their meditations, to these they will pay attention. In general, all that is excellent and laudable should be the constant object of every Christian's thoughts. In all things, at all times, in all places, the sanctification of the Christians should be evident.

To bring home this admonition, Paul cites his own example: What you have learned and received and heard and seen in me, this do; and the God of peace will be with you. Those are the things which he has just enumerated. He has the good conscience that he has walked in these virtues, that he has proved a good example to the Philippians under all conditions, in every way. The daily life and example of a pastor, as a sermon in deeds, is of the greatest importance in the work of the Church. In this manner the relation of the redeemed to God will be upheld. These points are necessary for the preservation of peace and harmony in the Church. The assurance of the presence of God, the God of peace, is given to believers if they follow the words of the apostle.
