At the Mount of Transfiguration, Jesus made it clear to the disciples that the kingdom is a present reality.  Generations before that moment, had gotten very used to looking back at the conquest of Moses or at looking forward to a someday kingdom.  We face the same challenges today, not dwelling on the past, we're always looking forward to a day that never comes… But living out of the kingdom that Jesus Christ afforded us in his death, burial, and resurrection.
