The pastor is involved in governments and helps. The pastor is head of the church. Christ is the Good Shepherd, the head of the body, the head of the whole church. (Pastor and shepherd mean the same thing.) The pastor of the local church and the local sheep is the undershepherd.
Just as government of your whole body emanates from your head, so the government of the local church heads up in the pastoral office. The government of the local church is not in the deacon. That’s the reason many Full Gospel churches are in trouble. They are losing their power and their anointing because, following other denominations, they allow men without the anointing and the call of God in their life run the church. And they are not equipped to do it. Deacons are placed in the church to serve and to help when they are called upon, not to provide spiritual leadership. This is the job of the pastor.
