Mosiah 16:5

5 But remember that he that persists in his own carnal nature, and goes on in the ways of sin and rebellion against God, remaineth in his fallen state and the devil hath all power over him. Therefore he is as though there was no redemption made, being an enemy to God; and also is the devil an enemy to God.

Mosiah 14:3-6

3 He is despised and rejected of men; a man of sorrows, and acquainted with grief; and we hid as it were our faces from him; he was despised and we esteemed him not.
4 Surely he has borne our griefs and carried our sorrows; yet we did esteem him stricken, smitten of God, and afflicted.
5 But he was wounded for our transgressions, he was bruised for our iniquities; the chastisement of our peace was upon him; and with his stripes we are healed.
6 All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquities of us all.

Mosiah 7:29

29 For behold, the Lord hath said: I will not succor my people in the day of their transgression, but I will hedge up their ways that they prosper not; and their doings shall be as a stumbling block before them.

2 Nephi 27:3

3. And all the nations that fight against Zion, and that distress her, shall be as a dream of a night vision; yea, it shall be unto them, even as unto a hungry man which dreameth, and behold he eateth but he awaketh and his soul is empty; or like unto a thirsty man which dreameth, and behold he drinketh but he awaketh and behold he is faint, and his soul hath appetite; yea, even so shall the multitude of all the nations be that fight against Mount Zion.

2 Nephi 15:12-14 & 20

12. And the harp, and the viol, the tabret, and pipe, and wine are in their feasts; but they regard not the work of the Lord, neither consider the operation of his hands.
13. Therefore, my people are gone into captivity, because they have no knowledge; and their honorable men are famished, and their multitude dried up with thirst.
14 Therefore, hell hath enlarged herself, and opened her mouth without measure; and their glory, and their multitude, and their pomp, and he that rejoiceth, shall descend into it.

20 Wo unto them that call evil good, and good evil, that put darkness for light, and light for darkness, that put bitter for sweet, and sweet for bitter!

2 Nephi 13:9

9. The show of their countenance doth witness against them, and doth declare their sin to be even as Sodom, and they cannot hide it. Wo unto their souls, for they have rewarded evil unto themselves!

2 Nephi 7:-1-2 & 11

1...Behold, for your iniquities have ye sold yourselves...
2. Wherefore, when I came, there was no man; when I called, yea, there was none to answer. O house of Israel, is my hand shortened at all that it cannot redeem, or have I no power to deliver? Behold, at my rebuke I dry up the sea, I make their rivers a wilderness and their fish to stink because the waters are dried up, and they die because of thirst.

11.Behold, all ye that kindle fire and compass yourselves about with sparks, walk in the light of your fire and in the sparks which ye have kindled. This shall ye have of mine hand--ye shall lie down in sorrow.

2 Nephi 4:(4) 26-29

4. For the Lord God hath said: Inasmuch as ye shall keep my commandments, ye shall prosper in the land; and inasmuch as ye will not keep my commandments ye shall be cut off from my presence.

26. O then, if I have seen so great things, if the Lord in his condescension unto the children of men hath visited men in so much mercy, why should my heart weep and my soul linger in the valley of sorrow, and my flesh waste away, and my strength slacken, because of mine afflictions?
27. And why should I yield to sin, because of my flesh? Yea, why should I give way to temptations, that the evil one have place in my heart to destroy my peace and afflict my soul? Why am I angry because of mine enemy?
28. Awake, my soul! No longer droop in sin. Rejoice, O my heart, and give place no more for the enemy of my soul.
29. Do not anger again because of mine enemies. Do not slacken my strength because of mine afflictions.

2 Nephi 2: (6-8) 11-13 (22-27)

6. Wherefore, redemption cometh in and through the holy Messiah, for he is full of grace and truth.
7. Behold, he offereth himself a sacrifice for sin, to answer the ends of the law, unto all those who have a broken heart and a contrite spirit, and unto none else can the ends of the law be answered.
8. Wherefore, how great the importance to make these things known unto the inhabitants of the earth; that they may know that there is no flesh that can dwell in the presence of God, save it be through the merits, and mercy, and grace of the Holy Messiah, who layeth down his life according to the flesh, and taketh it again by the power of the spirit; that he may bring to pass the resurrection of the dead, being the first that should rise.

11. For it must needs be, that there is an opposition in all things. If not so, my first-born in the wilderness, righteousness could not be brought to pass, neither wickedness, neither holiness nor misery, neither good nor bad. Wherefore, all things must needs be a compound in one; wherefore, if it should be one body it must needs remain as dead, having no life neither death, nor corruption nor incorruption, happiness nor misery, neither sense nor insensibility.
12. Wherefore, it must needs have been created for a thing of naught; wherefore there would have been no purpose in the end of its creation. Wherefore, this thing must needs destroy the wisdom of God and his eternal purposes, and also the power, and the mercy, and the justice of God.
13. And if ye shall say there is no law, ye shall also say there is no sin. If ye shall say there is no sin, ye shall also say there is no righteousness. And if there be no righteousness there be no happiness. And if there be no righteousness nor happiness there be no punishment nor misery. And if these things are not there is no God. And if there is no God we are not, neither the earth; for there could have been no creation of things, neither to act nor to be acted upon; wherefore, all things must have vanished away.

22. And now, behold, if Adam had not transgressed he would not have fallen, but he would have remained in the garden of Eden; and all things which were created must have remained in the same state in which they were after they were created, and they must have remained forever, and had no end.
23. And they would have had no children, wherefore, they would have remained in a state of innocence; having no joy, for they knew know sorrow, doing no good, for they knew no sin.
24. But behold, all things have been done in the wisdom of him who knoweth all things.
25. Adam fell that men might be and men are that they might have joy.
26. And the Messiah cometh in the fulness of time, that he may redeem the children of men from the fall, and because that they are redeemed from the fall they have become free forever, knowing good from evil, to act for themselves and not to be acted upon, save it be by the punishment of the law at the great and last day, according to the commandments which God hath given.
27. Wherefore, men are free according to the flesh, and all things are given them which are expedient unto man. And they are free to choose liberty and eternal life, through the great Mediator of all men, or to choose captivity and death, according to the captivity and power of the devil, for he seeketh that all men might be miserable like unto himself.

2 Nephi 1:13

13. O that ye would awake; awake from a deep sleep, yea, even from the sleep of hell, and shake off the awful chains by which ye are bound, which are the chains which bind the children of men, that they are carried away captive down to the eternal gulf of misery and woe.

Matthew 23:23-24

23. Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
24. Ye blind guides, which strain at a gnat, and swallow a camel.

David A. Bednar (October 2007 Conference)

But remission of sin is not the only or even the ultimate purpose of the gospel. To have our hearts changed by the Holy Spirit such that "we have no more disposition to do evil, but to do good continually" (Mosiah 5:2)... is the covenant responsibility we have accepted. This mighty change is not simply the result of working harder or developing greater individual discipline. Rather, it is the consequence of a fundamental change in our desires, our motives, and our natures made possible through the Atonement of Christ the Lord. Our spiritual purpose is to overcome both sin and the desire to sin, both the taint and the tyranny of sin.

Alma 22:18

18. O God, Aaron hath told me that there is a God; and if there is a God, and if thou art God, wilt thou make thyself known unto me, and I will give away all my sins to know thee, and that I may be raised from the dead, and be saved at the last day. And now when the king had said these words, he was struck as if he were dead.

D&C 20:37

37. And again, by way of commandment to the church concerning the manner of baptism--All those who humble themselves before God, and desire to be baptized, and come forth with broken hearts and contrite spirits, and witness before the church that they have truly repented of all their sins, and are willing to take upon them the name of Jesus Christ, having a determination to serve him to the end, and truly manifest by their works that they have received of the Spirit of Christ unto the remission of their sins, shall be received by baptism into his church.

Boyd K. Packer (date unknown)

I decided years ago that I was going to trust everybody. I had become suspicious of everybody because I had been misused and abused. I got so I didn't like myself very much and decided that I would trust everybody. If they weren't worthy of that trust they would have to prove it to me. I have been a lot happier since then.

D&C 64:9-11

9. Wherefore, I say unto you, that ye ought to forgive one another; for he that forgiveth not his brother his trespasses standeth condemned before the Lord; for there remaineth in him the greater sin.
10. I, the Lord, will forgive whom I will forgive, but of you it is required to forgive all men.
11. And ye ought to say in your hearts--let God judge between me and thee, and reward thee according to thy deeds.

Alma 40:10-11

10. Do not suppose, because it has been spoken concerning restoration, that ye shall be restored from sin to happiness; Behold, I say unto you, wickedness never was happiness.
11. And now, my son, all men that are in a state of nature, or I would say, in a carnal state, are in the gall of bitterness and in the bonds of iniquity; they are without God in the world, and they have gone contrary to the nature of God, therefore, they are in a state contrary to the nature of happiness.

Moroni 7:12-13

12. Wherefore, all things which are good cometh of God, and that which is evil cometh of the devil; for the devil is an enemy to God, and fighteth against him continually, and inviteth and enticeth to sin, and to do that which is evil continually.
13. But behold, that which is of God inviteth and enticeth to do good continually; wherefore, everything which inviteth and enticeth to do good, and to love God, and to serve him, is inspired of God.

2 Nephi 2:22-25

22. And now, behold, if Adam had not transgressed he would not have fallen, but he would have remained in the garden of Eden; and all things which were created must have remained in the same state in which they were after they were created, and they must have remained forever, and had no end.
23. And they would have had no children, wherefore, they would have remained in a state of innocence; having no joy, for they knew know sorrow, doing no good, for they knew no sin.
24. But behold, all things have been done in the wisdom of him who knoweth all things.
25. Adam fell that men might be and men are that they might have joy.
