The second property of God's people is holiness. "In the beauties of holiness;" a speech that is borrowed from the priest's garments under the law. Sometimes they were broidered with gold, sometimes they were all white, especially in the day of expiation. Not that ministers under the New Testament should have such garments as these, for these were representations to them, both of their inward holiness and of their outward holiness, by (beyond) others; but now all believers are priests as well as ministers are, and therefore such garments as these are not necessar. Indeed, if such garments as these had been necessar, then Christ and His apostles had done great wrong to themselves, who never used the like; and they had done great wrong to the kirk also in not appointing such garments to be worn by ministers. There be garments of glory in heaven, and garments of grace in the earth; that party-coloured garment spoken of in the Colossians, and this holiness whilk is spoken of here. Concerning whilk we will mark two things:--First, as people are a people of willingness in a good cause, so they must also be a people of holiness, or otherwise their willingness is only but for some worldly respects: therefore, I would have you with willingness to put on holiness. And, indeed, if we saw what holiness were, we needed not to be persuaded to put it on, we would do it willingly. For it has three parts in it--1. A purgation from former filthiness. 2. A separation from the world. If thou will be holy, then thou must be separate from the world; thou must strive to keep thyself from those whose garments are spotted with the flesh. 3. Holiness requires devotion or dedication to the Lord. When there is purgation from filthiness, separation from the world, and dedication to the Lord, there there is holiness and nowhere else.
