I. A PRINCIPLE. It is perfectly clear, as a matter of principle, that there ought to be holiness in all that is consecrated to God. He consecrated, or set apart unto Himself, the Sabbath day, and so He says, ‘Remember the Sabbath day, to keep it holy.’ The Temple, like our own churches, was consecrated to God, and therefore we read, ‘Holiness becometh Thine house for ever.’ The vessels of the Temple were dedicated, or sanctified to His service, and therefore they should not be touched by unhallowed hands, and the words of sacred Scripture are, ‘Be ye clean, that bear the vessels of the Lord.’ On these principles we none like to see a neglected church, a dishonoured Bible, or a careless attitude, in the house of God. On the same principles, we should all be profoundly humbled when unhallowed thoughts,—thoughts of the world, thoughts of vanity, of jealousy, or of self,—in any shape intrude into holy things, and corrupt those sacred hours which are set apart exclusively to God. But if this applies to consecration generally, how pre-eminently does it apply to such a consecration as that described in the text, in which we are said to be ‘sanctified in Christ Jesus.’ That sanctification is the introduction of the ruined sinner into a covenant union with the Son of God. If you have been thus sanctified in Christ Jesus, you no longer stand alone, to bear your own burden, or plead your own cause. You have been separated from the ruined world, and identified with the Lord Jesus; so that He represented you in bearing your curse when He suffered, and He now represents you at the right hand of the throne of God, while He pleads on your behalf. Thus you are cleansed from all legal guilt. You are sanctified by blood, and charged with no defilement. By the eternal covenant of God He is become your Head, so that in His death you died; in His life you live; in His acceptance you are justified; and in His glory you are glorified. But, if you are thus separated unto such a union with Him, is there any room left for one moment’s doubt as to what ought to be your character? If you are set apart by Him into this covenant union with Himself, you are set apart into a oneness of mind, of will, and of interest. He represents you in heaven, and you represent Him on earth; as God sees you in Him, so the world sees Him in you. You bear His name; you are sealed with the seal of the covenant; you are made a peculiar people unto the Son of God: and I am sure we must all see the justice of those words of the Apostle Peter, ‘As He who hath called you is holy, so be ye holy in all manner of conversation.’
