With The Prince's Poison Cup, R. C. Sproul continues his series of books designed to present deep biblical truths to children on their own level. Here he takes up the atonement, telling the story of a king whose people rebel and a prince who must drink a cup of poison in order to redeem them from the death their rebellion brought on.

The image is drawn from Christ's own language in Gethsemane about the cup he was given to drink, which makes the allegory unusually close to the thing it pictures. Framed as a grandfather's answer to a child's question about why medicine tastes bad. Fully illustrated in color, and a natural companion to The Lightlings.
