The Lord sent the resurrected John the Baptist to restore the Aaronic Priesthood. When John conferred this priesthood on Joseph Smith and Oliver Cowdery, he called them his "fellow servants" (D&C 13:1). President Gordon B. Hinckley (1910–2008) pointed out that John "did not place himself above Joseph and Oliver. He put them on his same level when he addressed them as 'my fellow servants.'" President Hinckley went on to say that a 12-year-old deacon can also be John's fellow servant.1
The Aaronic Priesthood holds the key of the ministering of angels (see D&C 13:1). As you live righteously and serve diligently, you can receive the ministering of angels to guide and strengthen you. Through your administration of the sacrament, you can help others receive this blessing as well.2
The Aaronic Priesthood "holds the keys of … the gospel of repentance, and of baptism by immersion for the remission of sins" (2 Nephi 31:17–18). Acting under the direction of your priesthood leaders, you can help people open this gate.
The Aaronic Priesthood includes the authority to administer the sacrament. When you prepare, bless, or pass the sacrament, you represent Jesus Christ (see 3 Nephi 18:1–12). You help your family members and friends remember Him, renew their covenants, and qualify for the companionship of the Holy Spirit.
Such opportunities require the work of priesthood men—men who are spiritually strong and who fulfill their priesthood duties.
