The Voyage of the Dawn Treader is a different kind of story than the first two we encountered in the Chronicles of Narnia because we are not immediately faced with imminent danger. Rather, the reader is drawn into a seafaring adventure. There is clearly an objective to the mission, but there is no evil witch to destroy or illegitimate king to remove from the throne. King Caspian outlines his mission to find seven men who had been practically (although I understand not formally) exiled by Caspian’s uncle Miraz to clear his own path to the throne. They were sent on a mission that had no hope.
“Well, on my coronation day, with Aslan’s approval, I swore an oath that, if once I established peace in Narnia, I would sail east myself for a year and a day to find my father’s friends or to learn of their deaths and avenge them if I could.”
Reepicheep had a separate mission to find Aslan’s country in the East that happened to coincide with Caspian’s, but the emphasis of this expedition for Caspian was to discover truth. He wasn’t quite sure where that journey would lead him. All he knew was that the seven men had traveled to the east, and he was going to follow them as far as he could.
The result could have been positive or negative. All seven men could have been alive, all seven men could have been dead or, as it turns out actually was the case, some could be alive while others were dead. Caspian did not settle for any of these three positions until he had actually proven which one was true.
This quest for truth needs to be our commitment as well. We might not like what we find at times. Caspian very well might have been happier if he had remained at home in Cair Paravel and simply convinced himself that all seven of those men must be fine in some tropical paradise. He would then perhaps conclude that he didn’t really need to go rescue them because they must be fine wherever they were.
He didn’t settle for that though, and the truth turned out to be somewhat less pleasant. Even though there were some happy reunions, two of the nobleman were assumed to be dead, one was insane, three were asleep and one turned out to be perfectly fine. With only one out of seven in fine shape, it surely would have been more comforting to remain in the delusion of the unknown. The entire crew experienced pain because of the discoveries they made.
That was not the point though. The main point was that it was important to discover truth. As I have written before, for Christians, we have nothing to fear by pursuing truth because we know who is the Truth. All honest pursuits of truth are going to lead to the same place.
