According to Ephesians 4, Christ has given gifts to the church. These gifts are people whom the Holy Spirit uses in specific ways. They are the apostles, prophets, evangelists, pastors and teachers. They work together to help the body to mature fully and in every aspect of body life. They do this by equipping everyone in the body to do the work of ministry (Ephesians 4:12-13). .
One of the reasons it is important for simple/organic churches to network together ties up with five-fold ministry. However, a network of churches is more likely to have all these gifts which Christ has given to the body to help it mature.
Within a network, therefore, if one of the churches recognizes that it is becoming inward looking, they could invite someone with an evangelistic gift to come and help them. If they are lacking in care for different people within their group, a pastor could help them to do this more effectively.
Christ has fully equipped the body to demonstrate his life to the world.
