The keynote speaker at the Church Growth Conference from which I have just returned was the Revd, John Daniel of the Presbyterian Church of New Zealand. (I met John when I was in NZ in 2009.) John said lots of interesting things, but one that particularly struck me was his definition of what is needed for change - and growth will bring change!
He identified three things. First, we need vision. Vision provides a snapshot of the desired future. Second, we need passion. Passion provides the energy. Third, we need dissatisfaction. Dissatisfaction provides the momentum - if we are not dissatisfied with the status quo, we won't change it.
