The theme of sacrifice is woven into C. S. Lewis’ book The Lion, the Witch, and the Wardrobe, and the filmmakers who adapted it for a 2005 movie kept this important element. In fact, they amplified it by including more examples than were given in the book. In the movie, we first see sacrifice during the air-raid. Edmund returns to the house to get his dad’s picture, and Peter accompanies him back to the safety of the Pevensies’ bomb shelter.
All of these lessons should be exhibited in our own lives. We do not have to duel the White Witch with swords, but oftentimes we need to sacrifice in other ways. Washing dishes, volunteering in thankless positions, being patient with those who are impatient--all of these are a sacrifice just as much as Oreius's charge or the Beavers' hospitality.
