In Pilgrim's Progress, Christian visits The Interpreter's House, where he sees several strange things that are analogies for the Christian faith. One of the things he sees is a fire in a fireplace, with someone (said to be Satan) continually pouring water on it, yet the fire doesn't go out. It's revealed that there's someone (said to be Christ) standing on the reverse side of the fireplace, pouring oil on the fire to keep it going.
Crayons drew a picture of The Interpreter's House on the narration scroll she's making for the book. In the room with the fireplace, you see someone pouring the bucket of water, and another guy hanging upside down from the ceiling. When I asked her about it, that's what she said: he's wearing special boots so he can walk on the ceiling and pour oil on the fire.
John Bunyan might have enjoyed that idea.
