During the fourteenth century Raynald III, was a duke in what is now Belgium. As the result of a violent quarrel, Raynald’s younger brother Edward successfully revolted against him. When Edward captured Raynald he built a room around him featuring windows and a door and promised him that the day he left the room his title and property would be returned to him.
The problem with this arrangement was that Raynald was grossly overweight and could not fit through the openings in the room. Raynald needed to lose weight before he could leave the room. Edward knew that his older brother could not control his appetite and sent him delicious food every day. As you may imagine, Raynald grew fatter during this time.
Anytime someone accused Duke Edward of treating Raynald cruelly he said: “My brother is not a prisoner. He may leave when he so wills.”
Raynald stayed in that room for ten years and wasn’t released until after Edward died in battle. By then his health was so ruined he died within a year. He was a prisoner of his own appetite.
Just as Raynald was enslaved by his appetite, sin will enslave all those who yield to it.
