Pilgrim's Progress §75: CHR.

CHR. Then said Christian, What means this? INTER. The Interpreter answered, This parlour is the heart of a man that was never sanctified by the sweet grace of the gospel; the dust is his original sin and inward corruptions, that have defiled the whole man. He that began to sweep at first, is the Law; but she that brought water, and did sprinkle it, is the Gospel. Now, whereas thou sawest, that so soon as the first began to sweep, the dust did so fly about that the room by him could not be cleansed, but that thou wast almost choked therewith; this is to shew thee, that the law, instead of cleansing the heart (by its working) from sin, doth revive, put strength into, and increase it in the soul, even as it doth discover and forbid it, for it doth not give power to subdue.
