When the great catastrophes soon enough came, the righteous were preserved. They had been called, motivated, and inspired to repent and to leave behind their wickedness. Nephi loved the people, but he had seen in vision how quickly they could fall away. He had already learned what was needed to apply the Atonement, and therefore he was personally instrumental and responsible for seeing that righteous people were there to meet the Savior when he came. 3 Nephi 7:17 says, “He did minister with power and with great authority.” “He did minister many things unto them” too sacred to record completely and too interwoven to speak of them only in part. In verse 18, it says that Nephi taught so well and with such a powerful spirit that “it were not possible that they could disbelieve his words, for so great was his faith on the Lord Jesus Christ that angels did minister unto him daily.” So, when the calamities struck and when Jesus appeared, Nephi and his righteous followers were prepared in many ways to receive the teachings of Jesus, to begin exercising the authority that he bestowed upon them, and to recognize who it was who came among them as an exalted being. When Jesus appeared at the Temple in Bountiful, he did not just come out of the blue, so to speak.
