After hearing the teachings of Alma, Limhi and all his people requested that they be baptized. They were so struck with the truth of Alma's words and exhortations-that they should remember always the goodness and loving kindness of God in freeing them from the slavery of the Lamanites-that they cried unanimously that they desired to walk obediently before God, and circumspectly with their brethren in doing those things the Lord required.
Alma, we presume, after conferring with Mosiah, granted their request for baptism and thereupon went forth into the water. As he had baptized their brethren when still they dwelt in Lehi-Nephi, Alma now baptized them in the waters that were provided for this very purpose. (See Chapter 18)
It should be noted that the same ritual observed by Alma in performing this sacred ordinance is the same as the practice celebrated today by the Church of Jesus Christ of Latter-day Saints. (See Vol.. I, p. 431, COMMENTARY ON THE BOOK OF MORMON)
Baptism is a commandment that must be complied with by everyone who desires membership in the Church of God. And everyone who is willing, and is baptized, becomes a member of His Church and is counted with the Saints of God. Even as it is today, this was the order of admittance into the Church and Kingdom of God in Mosiah's time.
