Scriptural Prophecies of the Restoration
31 ¶Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more.
Joseph Fielding Smith (Quorum of the Twelve)
The Lord has made great promises through his servants concerning these times. To Jeremiah the Lord said in speaking of this dispensation: [quotes Jeremiah 31:31-34].
In order that this prophecy may be fulfilled, many members of the Church will need to repent and be more diligent in the study of the scriptures and in their prayers and obedience to the laws and commandments of the gospel. If they fail to do these things they will be cut off from the presence of the Lord in that great day when he shall descend as Lord of lords and King of kings to take his place and sit on his throne to rule and reign. (CR, October 1963, 21)

We are laying the foundation for, and have already actually commenced, the greatest missionary undertaking ever destined to occur in any age of the earth's history. We are going forth by command of Deity to carry the knowledge of God and of his saving truths to all nations, to preach the gospel to every creature, and to give in due course, in this life or in the next every living soul the opportunity to hear and obey these saving principles.
The ultimate end of this missionary work will be to see the knowledge of God and his saving truths cover the earth ". . . as the waters cover the sea" (Isa. 11:9). The ultimate end of this missionary work will be reached when the day arrives in which it will no longer be necessary for every man to say to his brother or neighbor, "Know the Lord," for all shall know him from the greatest to the least (see Jer. 31:31-34).
Now, since we are engaged in the greatest missionary undertaking that has ever been planned as part of Deity's program, he has also placed in our hands the most effective, compelling, and persuasive missionary tool ever given to any people in any age. The name of this tool is the Book of Mormon. (CR, April 1961, 38)
Orson Pratt (Quorum of the Twelve)
It seems then that Paul understood, by the spirit of prophecy, that if the Gentiles apostatized [in his day], if they did not continue in the place where they were grafted, if they did not continue in the goodness of God, if they became highminded, they also were to be cut off, just as they have been for many long generations that are past; cut off from all the ancient blessings of the everlasting Gospel through the apostasy of their ancient fathers.
But the Lord intends to make a change, and that change is to send forth this Gospel from heaven to be preached to the nations of the Gentiles, to give them one more chance, if they will have it, to bring in their fullness; and when that time has come, and the servants of the Lord find that the balance of them harden their hearts and reject the Gospel of life and salvation, then the Lord will graft in all Israel, and they will be saved, being restored again to the tame olive tree, and bringing forth the fruits thereof. Thus will be fulfilled the ancient covenant that God made with them pertaining to the latter days. Have you read that covenant that Paul quotes from? One of the ancient prophets, Jeremiah, delivered the prophecy, as recorded in his 31st chapter—“Behold, the day shall come, that I will make a new covenant with the house of Israel, and with the house of Judah: Not according to the covenant which I made with their fathers when I took them by the hand and brought them forth out of the land of Egypt. And this is the covenant I will make with them, saith the Lord—I will write my law in their hearts, print it in their thoughts, and they shall all know me, from the least of them unto the greatest of them, saith the Lord.”
Now did all Israel and all Judah know the Lord, from the least of them to the greatest of them? Had they no more need to say, every man to his Jewish neighbor, know ye the Lord? Was that the case anciently, when the Lord offered them the covenant of the everlasting Gospel? No; instead of all Israel and all Judah knowing the Lord, from the least to the greatest, they were the
very ones that were cut off and lost the privileges of that covenant. But in the latter days when the fullness of the Gentiles is brought in by the proclamation of the Gospel committed by the angel, then is the time that the Lord will renew this covenant, and the same Gospel that he offered to them eighteen hundred years ago, and which they rejected, will be offered to them again, and all Israel will be saved.
