Mosiah 23

Because of the humility and obedience, the followers of Alma -

"...began to prosper exceedingly in the land..." (Book of Mormon Mosiah 23:19)

But even in great properity, Paul taught -

"...whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth..." (New Testament Hebrews 12:6)

We see this with the people of Alma that even as they began to prosper -

"Nevertheless the Lord seeth fit to chasten his people; yea, he trieth their patience and their faith." (Book of Mormon Mosiah 23:21)

Patience and faith go hand in hand. It is the test to be worthy to be called His son or daughter -

"Nevertheless—whosoever putteth his trust in him the same shall be lifted up at the last day. Yea, and thus it was with this people." (Book of Mormon Mosiah 23:22)

Because of His love for His children, great burdens were placed on the people of Alma to try their patience and faith. And as they were tested, as they continued in obedience with patience and faith, the Lord promised -

"...I will also ease the burdens which are put upon your shoulders, that even you cannot feel them upon your backs, even while you are in bondage; and this will I do that ye may stand as witnesses for me hereafter, and that ye may know of a surety that I, the Lord God, do visit my people in their afflictions.
15 And now it came to pass that the burdens which were laid upon Alma and his brethren were made light; yea, the Lord did strengthen them that they could bear up their burdens with ease..." (Book of Mormon Mosiah 24:14 - 15)

And with this, the people -

"...did submit cheerfully and with patience to all the will of the Lord." (Book of Mormon Mosiah 24:15)

It was not just a demonstration of patience and faith, but doing so cheerfully. And as the test was completed -

"...it came to pass that so great was their faith and their patience that the voice of the Lord came unto them again, saying: Be of good comfort, for on the morrow I will deliver you out of bondage." (Book of Mormon Mosiah 24:16)

Which miraculously He did. Paul taught -

"For ye have need of patience, that, after ye have done the will of God, ye might receive the promise." (New Testament Hebrews 10:36)

Elder Neal A. Maxwell taught -
“The necessity of our having this intriguing attribute is cited several times in the scriptures, including by King Benjamin, who clustered the attributes of a saint, and patience was a charter member of that cluster.

Patience is not indifference. Actually, it is caring very much, but being willing, nevertheless, to submit both to the Lord and to what the scriptures call the ‘process of time.’

Patience is tied very closely to faith in our Heavenly Father. Actually, when we are unduly impatient, we are suggesting that we know what is best—better than does God. Or, at least, we are asserting that our timetable is better than his. Either way we are questioning the reality of God’s omniscience, as if, as some seem to believe, God were on some sort of postdoctoral fellowship. . . .

We read in Mosiah about how the Lord simultaneously tries the patience of his people even as he tries their faith. One is not only to endure—but to endure well and gracefully those things which the Lord ‘seeth fit to inflict upon [us]’ (Mosiah 3:19), just as did a group of ancient American Saints who were bearing unusual burdens but who submitted ‘cheerfully and with patience to all the will of the Lord’ (Mosiah 24:15). . . .

The Lord has twice said: ‘And seek the face of the Lord always, that in patience ye may possess your souls, and ye shall have eternal life’ (D&C 101:38, italics added; see also Luke 21:19). Could it be that only when our self-control has become total do we come into true possession of our own souls?” (“Patience,” Ensign, Oct. 1980, p. 28).
