In saying “Your kingdom come,” we are acknowledging that faith in Jesus is not simply an idea or an emotion. It is a concrete reality of which we are to become part or else be out of step with the way things are now that God has come into the world in Jesus. When the kingdom comes, we are “to repent” (i.e. change, let go of our citizenship in the old kingdoms) and ‘believe the good news’ (i.e. join up, become part of the revolution).
