Note in Alma 23:8–13 the extent of the missionary success of Ammon and his brethren. Those converted Lamanites were blessed “to be a very industrious people; … and the curse of God did no more follow them” (v. 18).
Speaking about the missionary work yet to be done and the blessings that will come to those nations and people who accept the gospel, President Spencer W. Kimball said:
“If we are to fulfill the responsibility given to us by the Lord on the Mount of Olives to go into all the world and preach the gospel to every creature, then we will need to open the doors to these nations… . We’ve hardly scratched the surface. We need far more missionaries, and we need more countries that will think of us as being their friends and will give us an opportunity to come into their nations and give to their people the finest thing in the world—the gospel of Christ—which can be their salvation and their great happiness.
“… We will make them good citizens, we will make them good souls, and we will make them happy and joyous”
