"I was the lion…who forced you to join with Aravis. I was the cat who comforted you among the houses of the dead. I was the lion who drove the jackals from you while you slept. I was the lion who gave the Horses the new strength of fear for the last mile so that you should reach King Lune in time. And I was the lion you do not remember who pushed the boat in which you lay, a child near death, so that it came to shore where a man sat, wakeful at midnight, to receive you."
Yes, I do agree that this particular quotation from HHB is one of my most favourite bits. That in Narnia, at least, that there is a rhyme and reason for whatever happened to me. Some other bits I've enjoyed immensely, in HHB, at any rate, is King Lune's description of what it means to be a king, ie a leader. And I suspect this particular message, whether it is seen as Christian or not, is re-iterated elsewhere in the series.
"...to be first in every desperate attack and last in every desperate retreat, and when there is hunger in the land (as must be every now and then in bad years) to wear finer clothes and laugh louder over a scantier meal than any man in your land"
Christian leadership isn't really about domination of underlings. God is the leader over all. Or Aslan in Narnia. Not the king thinking he will live forever and can command instant obedience. Or the Tisroc's son's casual cruelty. Leadership is about example, getting others to co-operate in a team, vision, goals and taking the risks oneself. It is a good message to carry when put in charge of others for any reason. In various other ways in the Narnia series we see how the villains behave to others and how the good guys - Prince Caspian, himself, for instance - behave towards others.
