Doctrine and Covenants 121: 1-10. 23-33

How does the Savior help you to endure well?

"1 O God, where art thou? And where is the pavilion that covereth thy hiding place?

2 How long shall thy hand be stayed, and thine eye, yea thy pure eye, behold from the eternal heavens the wrongs of thy people and of thy servants, and thine ear be penetrated with their cries?

3 Yea, O Lord, how long shall they suffer these wrongs and unlawful oppressions, before thine heart shall be softened toward them, and thy bowels be moved with compassion toward them?

4 O Lord God Almighty, maker of heaven, earth, and seas, and of all things that in them are, and who controllest and subjectest the devil, and the dark and benighted dominion of Sheol—stretch forth thy hand; let thine eye pierce; let thy pavilion be taken up; let thy hiding place no longer be covered; let thine ear be inclined; let thine heart be softened, and thy bowels moved with compassion toward us.

5 Let thine anger be kindled against our enemies; and, in the fury of thine heart, with thy sword avenge us of our wrongs.

6 Remember thy suffering saints, O our God; and thy servants will rejoice in thy name forever.

7 My son, peace be unto thy soul; thine adversity and thine afflictions shall be but a small moment;

8 And then, if thou endure it well, God shall exalt thee on high; thou shalt triumph over all thy foes.

9 Thy friends do stand by thee, and they shall hail thee again with warm hearts and friendly hands.

10 Thou art not yet as Job; thy friends do not contend against thee, neither charge thee with transgression, as they did Job.

23 Wo unto all those that discomfort my people, and drive, and murder, and testify against them, saith the Lord of Hosts; a generation of vipers shall not escape the damnation of hell.

24 Behold, mine eyes see and know all their works, and I have in reserve a swift judgment in the season thereof, for them all;

25 For there is a time appointed for every man, according as his works shall be.

26 God shall give unto you knowledge by his Holy Spirit, yea, by the unspeakable gift of the Holy Ghost, that has not been revealed since the world was until now;

27 Which our forefathers have awaited with anxious expectation to be revealed in the last times, which their minds were pointed to by the angels, as held in reserve for the fulness of their glory;

28 A time to come in the which nothing shall be withheld, whether there be one God or many gods, they shall be manifest.

29 All thrones and dominions, principalities and powers, shall be revealed and set forth upon all who have endured valiantly for the gospel of Jesus Christ.

30 And also, if there be bounds set to the heavens or to the seas, or to the dry land, or to the sun, moon, or stars—

31 All the times of their revolutions, all the appointed days, months, and years, and all the days of their days, months, and years, and all their glories, laws, and set times, shall be revealed in the days of the dispensation of the fulness of times—

32 According to that which was ordained in the midst of the Council of the Eternal God of all other gods before this world was, that should be reserved unto the finishing and the end thereof, when every man shall enter into his eternal presence and into his immortal rest.

33 How long can rolling waters remain impure? What power shall stay the heavens? As well might man stretch forth his puny arm to stop the Missouri river in its decreed course, or to turn it up stream, as to hinder the Almighty from pouring down knowledge from heaven upon the heads of the Latter-day Saints." (Doctrine and Covenants 121: 1-10. 23-33)

And here's beginning part of the commentary entitled: "With God, adversity can “be for [my] good.” : 

"When we or people we love are suffering, it is normal to wonder if God is aware of us. As you read Doctrine and Covenants 121:1–6, think about times when you have had questions or feelings similar to Joseph Smith’s. What do you find in the Lord’s response that might help you when you have these questions or feelings? For example, in verses 7–10, 26–33, notice the blessings He promises. What do you think it means to “endure … well”? How does the Savior help you do this?"

Highlighted here are the blessings the Lord promises: 

"My son, peace be unto thy soul; thine adversity and thine afflictions shall be but a small moment; And then, if thou endure it well, God shall exalt thee on high; thou shalt triumph over all thy foes. 

Thy friends do stand by thee, and they shall hail thee again with warm hearts and friendly hands.Thou art not yet as Job; thy friends do not contend against thee, neither charge thee with transgression, as they did Job."

To endure well means to carry my burdens without complaining, and to even find peace and joy in whatever circumstances I find myself in. The Savior helps me do this as I turn to Him and follow His example. With Him, I am able to do all things. He lightens my load by strengthening me. He inspires me through the Spirit so I am able to know exactly what to do to rise above my challenges or afflictions. Every challenge is for my own good–it's shaping me so I can become my better version, more like my Savior and my Father in Heaven.
