They don't come along for the ride, but are ready for mule labor when needed. Faithful followers have spunk. A grouch in the rear is more dangerous to success than enemies in the front. Many church leaders have failed because their followers acted from like enemies than supporters. But one follower with spunk can inspire a legion of grouch followers.
Faithful followers have the ability to submit to a leader's vision.
Submission to leadership is just as much an acquired ability as any other talent. Submission especially does not come easy to folks in our individualistic American culture. But no true relationship, or Christian ministry, can happen without it. Followers help finish the job. Quitters profit much less often than cheaters.
