The salvation of the Lord shall be declared to every nation, kindred, tongue, and people...

According to Mosíah in The Book of Mormon the promise that salvation shall be declared to every nation, kindred, tongue and people has started to being fulfilled.

The Book of Mormon is a sacred scripture and a translation of an ancient record of scripture, written by ancient American prophets and translated by Joseph Smith. The book teaches that Jesus Christ visited the Americas after his resurrection and that the indigenous peoples of the Americas are among his descendants. The book was first published in 1830.

The book contains a lot of prophecies for the children of God. A prophecy is a prediction or statement about future events. Prophecies often contain messages or warnings about the future and can be found in religious texts. In the Bible, there are many prophecies, both fulfilled and unfulfilled. For example, there are prophecies in the Old Testament that predict the coming of a Messiah who would be born of a virgin and would be crucified for the sins of humanity. These prophecies were fulfilled in the life, death, and resurrection of Jesus Christ. Prophecy can also be found in other religious texts, such as the Book of Mormon, which contains prophecies about the coming forth of the book and the appearance of Christ in the Americas.

The way that the prophecy in Mosíah has started to be fulfilled is through the increase of missionaries all around the world. Missionary work can take many forms, such as door-to-door, running religious educational programs, or establishing places of worship. For example, the Church of Jesus Christ of Latter-day Saints sends out thousands of young men and women as full-time missionaries all over the world to spread the gospel of Jesus Christ.

The main purpose of the missionaries is to share the gospel with all the people that is willing to hear. So they can know how to have salvation.
