And this cleansing of our natures, persons, and duties, hath its whole foundation in the death of Christ. Hence our washing and purifying, our cleansing and purging, is ascribed to his blood and the sprinkling thereof meritoriously, this work is done, by the shedding of the blood of Christ; efficiently, by its sprinkling. The sprinkling of the blood of Christ proceedeth from the communication of the Holy Ghost; which he promiseth to us, as purchased by him for us. He is the pure water, wherewith we are sprinkled from all our sins, that spirit of judgment and burning that takes away the filth and blood of the daughters of Zion. And this is the first thing in the grace of sanctification; of which more afterward.
