Pole and Scrubb begin their adventures in Narnia, and we examine four key themes in the chapter: (1)There is no other stream (the living water Aslan offers is clearly a symbol for the living water Jesus describes in John's Gospel that He longs to give us, the only water which leads to life); (2) Sin and its consequences (Jill's sin leads to unimaginable consequences for Eustace, and she models taking responsibility rather than a victim mentality); (3) Aslan’s Call and Task (Aslan gives Jill an important and world-changing task that is FAR beyond her own gifts and capabilities); and (4) The Signs (Aslan tells Jill that there are Four Signs that will enable her to complete her task, which she must memorize and repeat day and night, lest she forget [strong echos of Deuteronomy 6).
