“Are there guardian angels? Do I have one assigned to me?” Liahona, Jan. 2012, 47
The term “guardian angel” is not used in the scriptures; instead, angels are spoken of as “ministering” (see Omni 1:25; Moroni 7:22–29). “Angels speak by the power of the Holy Ghost” (2 Nephi 32:3) and often share in the Holy Ghost’s mission to comfort, guide, protect the faithful, and reveal or confirm truth. Thus, the Holy Ghost Himself can be considered a guardian angel.
Elder Jeffrey R. Holland of the Quorum of the Twelve Apostles taught: “From the beginning down through the dispensations, God has used angels … in conveying love and concern for His children. … Seen or unseen they are always near” (“The Ministry of Angels,” Liahona and Ensign, Nov. 2008, 29).
The Lord has not revealed whether one specific angel is assigned to watch over each person, but you can be assured that divine protection and comfort are available. If you exercise faith, you will have God’s help, including angels sent to strengthen and comfort you and give you courage to do what is right.
