Thousands of Lamanites Are Converted to the Gospel, and None of Them Ever Fall Away

Alma 23:4–7

4 And now it came to pass that when the king had sent forth this proclamation, that Aaron and his brethren went forth from city to city, and from one house of worship to another, establishing churches, and consecrating priests and teachers throughout the land among the Lamanites, to preach and to teach the word of God among them; and thus they began to have great success.
5 And thousands were brought to the knowledge of the Lord, yea, thousands were brought to believe in the traditions of the Nephites; and they were taught the records and prophecies which were handed down even to the present time.
6 And as sure as the Lord liveth, so sure as many as believed, or as many as were brought to the knowledge of the truth, through the preaching of Ammon and his brethren, according to the spirit of revelation and of prophecy, and the power of God working miracles in them—yea, I say unto you, as the Lord liveth, as many of the Lamanites as believed in their preaching, and were converted unto the Lord, never did fall away.
7 For they became a righteous people; they did lay down the weapons of their rebellion, that they did not fight against God any more, neither against any of their brethren.

President Marion G. Romney said:

“In the twenty-third and twenty-fourth chapters of Alma we have a dramatic account of the power of the gospel changing almost a whole nation from a bloodthirsty, indolent, warlike people into industrious, peace-loving people. Of these people the record says that thousands were brought to a knowledge of the Lord, and that as many as were brought to a knowledge of the truth never did fall away. . . . That is the great message I want to leave here. It is the softening of the hearts that this gospel does to the people who receive it. . . . Now this remarkable transformation wrought in the hearts of these thousands of people was done in a very short period of time under the influence and power of the gospel of Jesus Christ. It would do the same thing today for all the peoples of the earth if they would but receive it.”
