"I often think...ministers are like watchmen—they see the fire and they give the alarm. Many of you are in danger as one in a burning house. Sometimes you wonder at our anxiety for you. Sometimes you say, "Why are you so harsh?" O, poor soul! It is because the house is on fire. O, then, can we speak too harshly'?—can we knock too loudly at the door of your consciences?" - Robert Murray M'Cheyne
