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.
A faithful follower keeps right on working and following until the job is done or someone has proven they can successful take over the mantle of the follower's ministry. A faithful follower protects his leader's moral character. Nathan was no yes man. He rebuked David knowing such an action might lead to his own death. And when David repented Nathan helped restore the King even comforting David in the pain and loss that the King's actions would soon bring on David's family.
