Mormon 3:20-22

" 20 And these things doth the Spirit manifest unto me; therefore I write unto you all. And for this cause I write unto you, that ye may know that ye must all stand before the judgment-seat of Christ, yea, every soul who belongs to the whole human family of Adam; and ye must stand to be judged of your works, whether they be good or evil;

 21 And also that ye may believe the gospel of Jesus Christ, which ye shall have among you; and also that the Jews, the covenant people of the Lord, shall have other witness besides him whom they saw and heard, that Jesus, whom they slew, was the very Christ and the very God.

 22 And I would that I could persuade all ye ends of the earth to repent and prepare to stand before the judgment-seat of Christ."

Mormon here describes the purposes of his writings.  They are:

1) To tell the whole human family that they will be judged by their works.

2) That all may believe the gospel of Jesus Christ.

3) That the Jews will have another witness that Jesus is the Christ and Savior of the world

4) To persuade all people to repent, thus being prepared for the inevitable judgement.

These are all unselfish reasons. I can tell that Mormon really loved the people and wanted them to be on good standings with the Lord.

Mormon 2:13

"But behold this my joy was vain, for their sorrowing was not unto repentance, because of the goodness of God; but it was rather the sorrowing of the damned, because the Lord would not always suffer them to take happiness in sin."

It's so sad that these people were so lost that they could not turn unto God to seek peace. They were so far away from the Spirit that they would not humble themselves. Their pride brought sorrow and lamentation.

4 Nephi verses 10-11

"And now, behold, it came to pass that the people of Nephi did wax strong, and did multiply exceedingly fast, and became an exceedingly fair and delightsome people.
And they were married, and given in marriage, and were blessed according to the multitude of the promises which the Lord had made unto them."

The Nephites lived the gospel and so were blessed.  I like how their strength is accorded to the many marriages that happened. Strength comes when there are families on the earth who love each other and live righteously. The family is so necessary in our day to preserve strength. To arm ourselves against the deceits of the destroyer. To have a place of refuge, a place where the teachings of Jesus are taught, discussed, and lived. I want my family to be like this and I am glad I was raised like this.

3 Nephi 28:10-11

"...and ye shall be even as I am, and I am even as the Father; and the Father and I are one;

And the Holy Ghost beareth record of the Father and me; and the Father giveth the Holy Ghost unto the children of men, because of me."

These verses explain the relationships of the Godhead. The Father and the Son are one, meaning that they are one in purpose. The Holy Ghost ministers unto men because of the Father and the Son.

Alma 42:29

"And now, my son, I desire that ye should let these things trouble you no more, and only let your sins trouble you, with that trouble which shall bring you down unto repentance."

I love this verse.  It simple explains that I should not worry about how others are acting or any other thing that I cannot control.  What I should worry about are my own sins and the need I have to repent and become clean before my Maker.  There's no point worrying about the unknown.  I jest need to exercise faith in those matters and focus on cleansing myself.

3 Nephi 22

3 Nephi 22:17

"No weapon that is formed against thee shall prosper..."

This is referring to persecution against the Church.  Throughout its history terrible things have happened. Though mobs don't storm against the Church today, there are many ideas against the Church that lead people astray. Things that may seem to harm the spread of the Gospel. Here though, Christ promises that none of these things will prosper.

3 Nephi 17

3 Nephi 17:6

"And he said unto them: Behold, my bowels are filled with compassion towards you."

After teaching the people, Jesus was ready to head back to his Father for a time.  The people did not want him to go though. Jesus sensed this and told them he was filled with compassion for them, so he stayed for a while longer. Jesus blessed their children, prayed for them, and did so many meaningful things for them. How wonderful that would have been!

3 Nephi 16

3 Nephi 16:17

"And then the words of the prophet Isaiah shall be fulfilled..."

Christ testifies that the words of the prophet Isaiah shall be fulfilled. Like all prophets, Isaiah speaks the words of Christ. Those prophesies will all come to pass in due time.

3 Nephi 15

3 Nephi 15:17

"That other sheep I have which are not of this fold; them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd."

Jesus Christ did not set up multiple churches;rather he made one church.  Why would there need to be different churches in different places in the world? That church was lost after He died, but it was restored through Joseph Smith. Jesus Christ is the head of the Church of Jesus Christ of Latter-day Saints. It is His church. He is our shepherd and we are of His fold.

3 Nephi 9

3 Nephi 9:2

" Wo, wo, wo unto this people; wo unto the inhabitants of the whole earth except they shall repent; for the devil laugheth, and his angels rejoice, because of the slain of the fair sons and daughters of my people; and it is because of their iniquity and abominations that they are fallen!"

Christ has been slain and His voice calms those in the Americas.  Much destruction befell the lands and in this verse Christ describes why. The devil swayed people to follow him and he did not care at all when they were destroyed. The Lord cares so much about His "fair sons and daughters" yet the "devil laugheth, and his angels rejoice".  Why would anyone follow the devil who rejoices in downfall?
