THE BROOM AND THE WATER
In his Pilgrim’s Progress, John Bunyan describes Interpreter’s house, which Pilgrim entered during the course of his journey to the Celestial City. The parlor of the house was completely covered with dust, and when a man took a broom and started to sweep, he and the others in the room began to choke from the great clouds of dust that were stirred up. The more vigorously he swept, the more suffocating the dust became. Then Interpreter ordered a maid to sprinkle the room with water, with which the dust was quickly washed away. Interpreter explained to Pilgrim that the parlor represented the heart of an unsaved man, that the dust was original sin, the man with the broom was the law, and the maid with the water was the gospel.
His point was that all the law can do with sin is to stir it up. Only the gospel of Jesus Christ can wash it away.
