"The knowledge of the secrets of the Kingdom." That sounds like a pretty big deal. What makes the disciples so special? Some have imagined this as a supernatural imbuing, some kind of special thing that was passed on in Jesus's secret society. I think it may be simpler than that, however. I think it maybe the very fact of living with Jesus, and the advantage that the disciples have in living with him and walking with him. For them, the stories are lived out. For others, only seeing Jesus in passing, parables are more critical.
