Why does the book end without us knowing anymore informantion on David and his mother?

Inthink the themes of the book involve how David has developed rather than simply the end result. Aside from affirming the narrative's thematic emphasis on the power of both faith and perseverance, the words of David's mother also affirm the one thing that has sustained David from the very beginning of his quest. This is the gift given to him, as narration reveals, by Johannes right from David's early days in the concentration camp and self-affirmed by David in every prayer - the gift of identity, of individuality, of self-hood, and most importantly of freedom to choose. This gift was at first defined and fiercely clung to only by name but later, as David's mother unwittingly acknowledges, defined by all the things he is, all the things he has seen, all the things he has dreamed, and all the things he has believed in.
