Some of the Greatest Missionaries with Enormous Numbers of Converts to the LORD

[Still_Small_Voice]

Some of the greatest missionaries for Christ were Nephi and Lehi written about in the books of Helaman and III Nephi.  Here a small portion of an account given of their missionary labors in Helaman chapter 5:

17 And it came to pass that they did preach with great power, insomuch that they did confound many of those dissenters who had gone over from the Nephites, insomuch that they came forth and did confess their sins and were baptized unto repentance, and immediately returned to the Nephites to endeavor to repair unto them the wrongs which they had done.
18 And it came to pass that Nephi and Lehi did preach unto the Lamanites with such great power and authority, for they had power and authority given unto them that they might speak, and they also had what they should speak given unto them—

19 Therefore they did speak unto the great astonishment of the Lamanites, to the convincing them, insomuch that there were eight thousand of the Lamanites who were in the land of Zarahemla and round about baptized unto repentance, and were convinced of the wickedness of the traditions of their fathers.

After these missionary labors Nephi and Lehi went to the land of Nephi to preach to others but were captured and thrown into a prison.  After a miraculous spiritual spiritual experience in the prison about three hundred more people were converted.  These three hundred also began missionary labors.
 
50 And it came to pass that they did go forth, and did minister unto the people, declaring throughout all the regions round about all the things which they had heard and seen, insomuch that the more part of the Lamanites were a convinced of them, because of the greatness of the evidences which they had received.

51 And as many as were a convinced did lay down their weapons of war, and also their hatred and the tradition of their fathers.    

1 And it came to pass that when the sixty and second year of the reign of the judges had ended, all these things had happened and the Lamanites had become, the more part of them, a righteous people, insomuch that their a righteousness did exceed that of the Nephites, because of their firmness and their steadiness in the faith. -- Helaman chapter 6

The more part of the Lamanite nation after this laid down their arms and there was peace in the land.  The Nephites and Lamanites began to have free interactions with each other as recorded in Helaman chapter 6.

7 And behold, there was peace in all the land, insomuch that the Nephites did go into whatsoever part of the land they would, whether among the Nephites or the Lamanites.
8 And it came to pass that the Lamanites did also go whithersoever they would, whether it were among the Lamanites or among the Nephites . . .
