“I appeal to every one, whether this is not the very course they would take in case of exposedness to any great temporal calamity? If any of you who are heads of families saw one of your children in a house all on fire, and in imminent danger of being soon consumed in the flames, yet seemed to be very insensible of its danger, and neglected to escape after you had often called to it—would you go on to speak to it only in a cold and indifferent manner? Would not you cry aloud, and call earnestly to it, and represent the danger it was in, and its own folly in delaying, in the most lively manner of which you was capable? If you should continue to speak to it only in a cold manner, as you are wont to do in ordinary conversation about indifferent matters, would not those about you begin to think you were bereft of reason yourself? This is not the way of mankind in temporal affairs of great moment, that require earnest heed and great haste, and about which they are greatly concerned. They are not wont to speak to other of their danger, and warn them but a little or in a cold and indifferent manner. Nature teaches men otherwise. If we who have the care of souls, knew what hell was, had seen the state of the damned, or by any other means had become sensible how dreadful their case was—and at the same time knew that the greater part of men went thither, and saw our hearers not sensible of their danger—it would be morally impossible for us to avoid most earnestly setting before them the dreadfulness of that misery, and their great exposedness to it, and even to cry aloud to them."
Jonathan Edwards, concerning preaching on hell
