how is david different at the begging and end of the novel? how does david stay the same (paragraph)

I think David is actually a fairly static character. He has a goodness to him from beginning to end. He is a Christ-figure and never deviates from this role. The only thing that does develop is David's faith. I think that David's faith develops. David's entire journey, both physical and mental/emotional/spiritual/psychological, is triggered and motivated by faith - in fact, by several different sorts of faith. There is, for David, the essential faith that his life and identity are worth living, preserving, and enacting. There is his faith, despite his suspicions, that the camp commandant is giving him correct advice when he says to go to Denmark. There is the fundamental faith that, along the way, he will find help and support, food and transportation and money.
