A Mysterious Knowledge (Matthew 13:10-16)

One would think that as Christ enters history that his desire is to start a movement.  He is the one who is bringing in the kingdom, and so one who brings in the kingdom will need citizens to be part of the kingdom.  It would seem wise to make the kingdom accessible.  However, Christ speaks in cryptic language, and seems to do more to drive people away rather than the bring them near.  Why does Christ speak in parables?
