A cog is a "gear" that when joined with other cogs allows energy to be shifted from a point of creation to a point of application. Just like in a motorcar, the engine produces the necessary power need to move the vehicle, but that power would be utterly useless if not "channeled" somehow to the wheels. Hence, the cog. Through the car's gearbox the energy produced by the engine is transferred to the road and, voila', we are going places!
Bosko's C.O.G.G.s are any form of ministry within the church family who will transmit the Lord's power from the centre of His church to the world outside - through caring and outreaching. "Caring" is to make sure the members of Bosko Family are nurtured, protected, fed and loved. "Outreach" is to make sure that we never forget our Lord's commission to go to Jerusalem (Hermanus) and to Judea (the surrounding regions) and to Samaria (other groups and cultures) and to the ends of the world (missions). Every one in Bosko has a mission, a vision or an assignment.
