1 Nephi 13:40

And the angel spake unto me, saying: These last records which thou hast seen among the Gentiles, shall establish the truth of the first, which is of the twelve apostles of the Lamb, and shall make known the plain and precious things which have been taken away from them; and shall make known to all kindreds, tongues, and people, that the Lamb of God is the Eternal Father and the Saviour of the world; and that all men must come unto Him, or they cannot be saved;

The angel spoke to me and said: “These last records that you have seen among the Gentiles will prove the truth of the first, which are from the twelve apostles of the Lamb. They will make known the clear and precious things that have been taken away from them. They will make known to all families, languages, and people that the Lamb of God is the Eternal Father and the Savior of the world. All men must come to Him, or they cannot be saved.”

The angel said: “These later records you see among the Gentiles will confirm the first records from the twelve apostles. They’ll restore the clear, precious truths that were removed. They’ll show every nation, language, and people that the Lamb of God is the Eternal Father and the world’s Savior. Everyone must come to him or they can’t be saved.”
