This a helpful parable from Robert Fitts about the role of leaders in the local church.
In every car there are two motors – one runs on gasoline and the other on electricity. The gasoline motor is huge in comparison to the electric motor; but it is the tiny little electric motor that is designed to start the gasoline motor, and the gasoline motor is designed to provide the power to move the car. As soon as the big motor engages, the little motor disengages. If it did not, it would burn out in a matter of minutes.
The apostle, prophet, evangelist, pastor, and teacher are servants to the Body of Christ to act as initiators (starters) to get the body functioning. Just as the starter motor disengages as soon as the big motor starts, so it is with the wise leader. If he stays engaged he will burn out, just as a starter motor would do if it did not disengage after starting the big motor.
As long as the little starter motor is trying to move the car by the power of a single battery, the car will never function as it was designed to function. It is only the 350 horsepower motor that was designed to move the car, and it is only the Body of Christ that has been designed to build up the Body unto the measure of the fulness of Christ. Only as the Body of Christ is released to minister to itself will it ever attain unto the fullness of the maturity in Christ.
