Ephesians 4:11-12 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:

     In the church, officers are appointed as co-workers with God for the edification of the body of Christ. In the Lord's plan human beings have been made necessary to one another. To every one God has entrusted talents. These talents we are to use to help one another to walk in the narrow path. In this work each one is connected with the other, and all are united with Christ. It is by unselfish service that we improve and increase our talents.
     The members of the church of God on this earth are as the different parts of a machine, all closely related to one another, and all closely related to and dependent on one great center. There is to be unity in diversity. No member of the Lord's firm can work successfully in independence, detached from the others. . . . All are to use their entrusted capabilities in His service, that each may minister to the perfection of the whole. Each is to work under the supervision of God.
