Faith
More than any of the other Chronicles of Narnia, the theme of faith is present at literally every plot twist and event that occurs. Things in Narnia have gone awry because some of its peoples have started to lose faith in Aslan, for example, the dwarfs and also Shift the ape. Other things go horribly wrong because of a strength of faith, for example, the mice, and the bears, really don't want to do what the ape tells them and admit they would rebel outright if it wasn't for the fact that he had shown them Aslan and as unlikely as the orders sound they come from Aslan so they have to be obeyed. The ape, who has no faith in anything spiritual at all, also plays off the Narnians and the Calormenes by telling them their Gods are one and the same. At the end of the novel those who have strong faith and goodness of heart follow Aslan and receive eternal life in Heaven; those who follow Tash receive eternal damnation.
The Christian Religion
Christianity is allegorized in this novel especially with the introduction of Heaven and the fact that the children have died and therefore ended up there. The tenets of how to live a good Christian life are also part of this theme; the Unicorn is wildly happy once they get to Heaven as he states this is what he has been searching for all his life, showing that he has wanted to walk alongside Aslan. Similarly Aslan assures the Calormene who want to go with him that if they have done good in the name of Tash then it is a tribute in Aslan's name and if they have done wrong in Aslan's name they still belong to Tash. When the Pevensie children tell Tirian that Susan is not with them because she no longer believes in Narnia this is showing that if one does. It believe in Heaven one does not get to go there.
Political Strategy
Politicians are not shown in a good light in this novel and their strategy is one of the themes of the book. There are basically two types of politician in the novel; the ones who want to take over Narnia, and the others who want to see Narnia destroyed all together. Shift is an example of a politician who identifies the low information members of the community and simply forces his own will on them. He makes alliances with the enemy because he feels it is to his benefit. Ginger is far more Machiavellian and is friend to all sides and loyal to none. The novel shows how the politicians who want to get something for themselves are successful but the country suffers. The political dealings in the novel are complex and show the worst of people's natures.
Importance of Loyalty
One of the most touching things in the book is the moment when the dogs race to Tirian and jump up on him, excitedly licking him. Another is when the horses sacrifice themselves to come to his aid. The importance of loyalty is one of the themes in the book and ultimately those who are loyal are rewarded, and their loyalty values. It is notable that the loyalty of one dwarf outweighs the treachery of every other one.
