While congregational transformation requires the initiating leadership of the senior or solo pastor and any other staff, that is not enough. Nor will that usually sustain the transition and changes needed for transformation.
Laypersons must be organized for service. They must feel ownership of the transformation movement. They must be captivated by the vision God is seeking to impart to the congregation.
The amazing thing is that empowering laity can also result in new perspectives, new ideas, new resources, and new energy invested in the transformation movement. God is clearly working through lay leaders as well as pastoral leaders.
