"Then I saw in my dream that the Interpreter took Christian by the hand, and led him into a place where was a fire burning against a wall, and one standing by it always casting much water upon it to quench it; yet did the fire burn higher and hotter."
Interpreter: "This fire is the work of grace that is wrought in the heart; he that casts water upon it to extinguish and put it out, is the devil: but in that thou seest the fire notwithstanding burn higher and hotter, thou shalt also see the reason of that. So he had him about to the backside of the wall, where he saw a man with a vessel of oil in his hand, of the which he did also continually cast, but secretly, into the fire." "This is Christ, who continually with the oil of His grace maintains the work already begun in the heart: by the means of which, notwithstanding what the devil can do, the souls of His people prove gracious still."
- John Bunyan, The Pilgram's Progress
