To do the work of the Lord on the earth. God's chosen servants must be called of God in order to minister in his work. When true ministers do the Lord's will, they represent the Lord in their official duties and act as his agents (D&C 64: 29), thus conducting the work necessary for the salvation of mankind. The Lord has given Apostles, prophets, evangelists, high priests, seventies, elders, bishops, priests, teachers, deacons, helps, and governments for the perfecting of the Saints, for the work of the ministry (Eph. 4: 11-16; 1 Cor. 12: 12-28; D&C 20; 107).

The Son of Man came not to be ministered unto, but to minister, Matt. 20: 26-28. I have appeared to make thee a minister and a witness, Acts 26: 16-18. God is not unrighteous to forget your labor of love in that ye have ministered to the Saints, Heb. 6: 10. If any man minister, let him do it as of the ability which God giveth, 1 Pet. 4: 10-11. They taught, and did minister one to another, 3 Ne. 26: 19. It is the duty of the Twelve to ordain evangelical ministers, D&C 107: 39-40. A high priest may be set apart unto the ministering of temporal things, D&C 107: 71-72. These seventy are to be traveling ministers, D&C 107: 93-97.
