In 1 Nephi 11-14 the prophet Nephi has a vision of the Tree of Life and its interpretation. An unnamed angel takes him through the vision, acting as a teacher explaining various parts of the vision to him. “And it came to pass that I saw the heavens open; and an angel came down and stood before me” (1 Nephi 11:14). The angel showed Nephi that the Son of God would be born of Mary, the baptism of Jesus, the Twelve Apostles, the miracles of Jesus, as well as his crucifixion (1 Nephi 11:10-33). Nephi finishes writing his account of his experience with the angelic guide: “And I bear record that I saw the things which my father saw, and the angel of the Lord did make them known unto me” (1 Nephi 14:29).
The apostle John also has an experience with an angel that served as a guide to him. He says, “There came one of the seven angels which had seven vials, and talked with me, saying unto me, Come hither; I will shew unto thee the judgment of the great whore that sitteth upon many waters” (Revelation 17:1). After this, the angel carried John “away in the spirit into the wilderness” (Revelation 17:3). During this vision, the angel served as a guide to John regarding things that he had seen in vision. The angel told John, “I will tell thee the mystery of the woman, and of the beast that carrieth her, which hath the seven heads and ten horns (Revelation 17:7). The angel’s interpretation of this vision is found in Revelation 17:7-18.
