Last week, Christiana, her children, and Mercy received what every pilgrim soon learns to prize: a faithful guide. They had reached the Interpreter’s House. They had been welcomed, instructed, refreshed, and clothed. Then, as they prepared to continue, the Interpreter called for one of his servants: “Then said the Interpreter to one of his servants, Take sword, and helmet, and shield; and take these my daughters, and conduct them to the house called Beautiful.”
