In order to obey the injunctions, those to whom Peter writes are urged to put away all such things as are contrary to the spirit of love. In order to do this they will long for the sustenance of the Word.
All this leads to the subject of the testing of their confidence. Describing the Church as a building, Peter declared the cornerstone is the living Christ, from whom the preciousness is derived, which is to manifest the excellencies of God to the world. The description of the Church is systematic and exhaustive. It is a race, and this suggests its life principle. It is a priesthood, and so has right of access to God. It is a nation, and so is under His government. It is a possession, and so is actually indwelt by Him.
The application of these principles immediately follows. The first result will be abstention from fleshly lusts, and behaving themselves among outsiders in a seemly manner; they will silence slander, and vindicate God. Peter then showed what should be the relation of the separated nation to the world powers. It was to be submission to authority. In short, crisp sentences he charged them, “Honour all men. Love the brotherhood. Fear God. Honour the king.”
Then he showed how these things would apply. Servants will yield obedience to their masters as unto Christ. The service rendered will be the opportunity of manifesting the very Spirit of Christ.
