In the next section of Alan Hirsch’s book The Forgotten Ways he explains what he terms organic systems.  He starts by showing that Jesus talked in mostly organic terms about organisation using imagery of fields or vines.  He insists that this was not just a surface illustration but a deeper one.

Organic systems have embedded within each cell the information we would call DNA.  In the same way an active church in the mode of the book of Acts needs to develop its members into people who understand what their calling is and are ‘living it’.  These people (who see God in all of their lives because God is one and is everywhere) will communicate the gospel of God through their social networking.  They will then need to train up the contacts that they make by forming new cells which then are well enough trained and living spiritually disciplined lives that they reproduce.

The leadership and inspiration for this kind of organization does not come from on high through an hierarchy.  It comes from the individuals in the group seeing their calling and communicating their enthusiasm for Christ life-on-life in smaller groups.
