The body of believers in a local congregation must, by necessity, work as a unit. If one part of the body suffers, the whole body suffers. If one part of the body succeeds, the whole-body benefits. There are many distinct parts or roles that Christians can play within the church. When each of these roles are fulfilled in ways that honor God, the local congregation becomes an effective, life-giving “organism.” God not only appoints people to certain roles but gives them the desire and ability to fruitfully play those roles out.
