Mosiah’s Sons’ Motivation for Serving Their Missions Is Charity
Alma 17:9–12, 16
9 And it came to pass that they journeyed many days in the wilderness, and they fasted much and prayed much that the Lord would grant unto them a portion of his Spirit to go with them, and abide with them, that they might be an instrument in the hands of God to bring, if it were possible, their brethren, the Lamanites, to the knowledge of the truth, to the knowledge of the baseness of the traditions of their fathers, which were not correct.
10 And it came to pass that the Lord did visit them with his Spirit, and said unto them: Be comforted. And they were comforted.
11 And the Lord said unto them also: Go forth among the Lamanites, thy brethren, and establish my word; yet ye shall be patient in long-suffering and afflictions, that ye may show forth good examples unto them in me, and I will make an instrument of thee in my hands unto the salvation of many souls.
12 And it came to pass that the hearts of the sons of Mosiah, and also those who were with them, took courage to go forth unto the Lamanites to declare unto them the word of God. . . .
16 Therefore, this was the cause for which the sons of Mosiah had undertaken the work, that perhaps they might bring them unto repentance; that perhaps they might bring them to know of the plan of redemption.
The Prophet Joseph Smith said:
“Love is one of the chief characteristics of Deity, and ought to be manifested by those who aspire to be the sons of God. A man filled with the love of God, is not content with blessing his family alone, but ranges through the whole world, anxious to bless the whole human race.”
