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.

Jacob 7:14

14 And I said unto him: What am I that I should tempt God to show unto you a sign in the thing which thou knowest to be true? Yet thou wilt deny it, because thou art of the devil. Nevertheless, not my will be done; but if God shall smite thee, let that be a sign unto thee that he has power, both in heaven and in earth; and also, that Christ shall come. And thy will, O Lord, be done, and not mine.

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 26:(22)24-25 & 29

22. ... and [the devil] leadeth them by the neck with a flaxen cord, until he bindeth them with his strong cords forever.

24. He doeth not anything save it be for the benefit of the world; for he loveth the world, even that he layeth down his own life that he may draw all men unto him. Wherefore, he commandeth none that they shall not partake of his salvation.
25. Behold, doth he cry unto any saying: Depart from me? Behold, I say unto you, Nay; but he saith: Come unto me all ye ends of the earth, buy milk and honey, without money and without price.

29. He commandeth that there shall be no priestcrafts; for, behold, priestcrafts are that men preach and set themselves up for a light unto the world, that they may get gain and praise of the world; but they seek not the welfare of Zion.

2 Nephi 24:9-12

9. Hell from beneath is moved to meet thee at thy coming; it stirreth up the dead for thee, even all the chief ones of the earth; it hath raised up from their thrones all the kings of the nations.
10. All they shall speak and say unto thee: Art thou become weak as we? Art thou become like unto us?
11. Thy pomp is brought down to the grave; the noise of thy viols is not heard; the worm is spread under thee, and the worms cover thee.
12. How art thou fallen from heaven, O Lucifer, son of the morning! Art thou cut down to the ground, which did weaken the nations!

2 Nephi 9:21 & 28-29

21. And he cometh into the world that he may save all men if they will hearken unto his voice; for behold, he suffereth the pains of all men, yea, the pains of every living creature, both men, women, and children, who belong to the family of Adam.

28. O that cunning plan of the evil one! O the vainness, and the frailties, and the foolishness of men! When they are learned they think they are wise, and they hearken not unto the counsel of God, for they set it aside, supposing they know of themselves, wherefore, their wisdom is foolishness, and it profiteth them not. And they shall perish.
29. But to be learned is good if they hearken unto the counsels of God.

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 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.

Dieter F. Uchtdorf (April 2007 Conference)

Satan will try to make us believe that our sins are not forgiven because we can remember them. Satan is a liar...God did not promise that we would not remember our sins. Remembering will help us avoid making the same mistakes again. But if we stay true and faithful, the memory of our sins will be softened over time...

Never is the soul nobler and more courageous than when we forgive. This includes forgiving ourselves.

Mosiah 3:5-8

5. For behold, the time cometh, and is not far distant, that with power, the Lord Omnipotent who reigneth, who was, and is from all eternity to all eternity, shall come down from heaven among the children of men, and shall dwell in a tabernacle of clay, and shall go forth amongst men, working mighty miracles, such as healing the sick, raising the dead, causing the lame to walk, the blind to receive their sight, and the deaf to hear, and curing all manner of diseases.
6. And he shall cast out devils, or the evil spirits which dwell in the hearts of the children of men.
7. And lo, he shall suffer temptations, and pain of body, hunger, thirst, and fatigue, even more than man can suffer, except it be unto death; for behold, blood cometh from every pore, so great shall be his anguish for the wickedness and abominations of his people.
8. And he shall be called Jesus Christ, the Son of God, the Father of heaven and earth, the Creator of all things from the beginning; and his mother shall be called Mary.

2 Nephi 32:8-9

8. And now, my beloved brethren, I perceive that ye ponder still in your hearts; and it grieveth me that I must speak concerning this thing. For if ye would hearken unto the Spirit which teacheth a man to pray, ye would know that ye must pray; for the evil spirit teacheth not a man to pray, but teacheth him that he must not pray.
9. But behold, I say unto you that ye must pray always, and not faint; that ye must not perform anything unto the Lord save in the first place ye pray unto the Father in the name of Christ, that he will consecrate thy performance unto thee, that thy performance may be for the welfare of thy soul.

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 2:26-27

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.

D&C 35:24

Keep all the commandments and covenants by which ye are bound, and I will cause the heavens to shake for your good, and Satan shall tremble and Zion shall rejoice upon the hills and flourish.

D&C 10:4-5 & 43

4. Do not run faster or labor more than you have strength and means provided to enable you to translate, but be diligent unto the end.
5. Pray always, that you may come off conqueror; yea, that you may conquer Satan, and that you may escape the hands of the servants of Satan that do uphold his work.

43. I will not suffer that they shall destroy my work; yea, I will show unto them that my wisdom is greater than the cunning of the devil.
