Mosiah 11:24-25

24 Yea, and it shall come to pass that when they shall cry unto me I will be slow to hear their cries; yea, and I will suffer them that they be smitten by their enemies.
25 And except they repent in sackcloth and ashes, and cry mightily to the Lord their God, I will not hear their prayers, neither will I deliver them out of their afflictions; and thus saith the Lord, and thus hath he commanded me.

Jacob 6:5/12

5 Wherefore, my beloved brethren, I beseech of you in words of soberness that ye would repent, and come with full purpose of heart, and cleave unto God as he cleaveth unto you. And while his arm of mercy is extended towards you in the light of the day, harden not your hearts.

12 O be wise; what can I say more?

2 Nephi 31:13/19-20

13 Wherefore, my beloved brethren, I know that if ye shall follow the Son, with full purpose of heart, acting no hypocrisy and no deception before God, but with real intent, repenting of your sins, witnessing unto the Father that ye are willing to take upon you the name of Christ, by baptism—yea, by following your Lord and your Savior down into the water, according to his word, behold, then shall ye receive the Holy Ghost; yea, then cometh the baptism of fire and of the Holy Ghost; and then can ye speak with the tongue of angels, and shout praises unto the Holy One of Israel.

19 And now, my beloved brethren, after ye have gotten into this strait and narrow path, I would ask if all is done? Behold, I say unto you, Nay; for ye have not come thus far save it were by the word of Christ with unshaken faith in him, relying wholly upon the merits of him who is mighty to save.
20 Wherefore, ye must press forward with a steadfastness in Christ, having a perfect brightness of hope, and a love of God and of all men. Wherefore, if ye shall press forward, feasting upon the word of Christ, and endure to the end, behold, thus saith the Father: Ye shall have eternal life.

2 Nephi 30:2

2 For behold, I say unto you that as many of the Gentiles as will repent are the covenant people of the Lord; and as many of the Jews as will not repent shall be cast off; for the Lord covenanteth with none save it be with them that repent and believe in his Son, who is the Holy One of Israel.

2 Nephi 10:23-24

23. Therefore, cheer up your hearts, and remember that ye are free to act for yourselves--to choose the way of everlasting death, or the way of eternal life.
24. Wherefore, my beloved brethren, reconcile yourselves to the will of God, and not to the will of the devil and the flesh. And remember, after ye are reconciled unto God, that it is only in and through the grace of God that ye are saved.

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.

1 Nephi 10:17-19

17. And it came to pass after I, Nephi, having heard all the words of my father, concerning the things which he saw in a vision, and also the things which he spake by the power of the Holy Ghost, which power he received by faith on the Son of God--and the Son of God was the Messiah who should come--I, Nephi, was desirous also that I might see, and hear, and know of these things, by the power of the Holy Ghost, which is the gift of God unto all those who diligently seek him, as well in times of old as in the time that he should manifest himself unto the children of men.
18. For he is the same yesterday, today, and forever; and the way is prepared for all men from the foundation of the world, if it so be that they repent and come unto him.
19. For he that diligently seeketh shall find; and the mysteries of God shall be unfolded unto them, by the power of the Holy Ghost, as well in these times as in times of old, and as well in times of old as in times to come; wherefore, the course of the Lord is one eternal round.

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.

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.

The Family: A Proclamation to the World 7

The family is ordained of God. Marriage between man and woman is essential to His eternal plan. Children are entitled to birth within the bonds of matrimony, and to be reared by a father and a mother who honor marital vows with complete fidelity. Happiness in family life is most likely to be achieved when founded upon the teachings of the Lord Jesus Christ. Successful marriages and families are established and maintained on principles of faith, prayer, repentance, forgiveness, respect, love, compassion, work, and wholesome recreational activities. By divine design, fathers are to preside over their families in love and righteousness and are responsible to provide the necessities of life and protection for their families. Mothers are primarily responsible for the nurture of their children. In these sacred responsibilities, fathers and mothers are obligated to help one another as equal partners. Disability, death, or other circumstances may necessitate individual adaptation. Extended families should lend support when needed.

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.

Mosiah 4:9-10

9. Believe in God; believe that he is, and that he created all things, both in heaven and in earth; believe that he has all wisdom, and all power, both in heaven and in earth; believe that man doth not comprehend all the things which the Lord can comprehend.
10. And again, believe that ye must repent of your sins and forsake them, and humble yourselves before God; and ask in sincerity of heart that he would forgive you; and now, if you believe all these things see that ye do them.

D&C 18:10-16

10. Remember the worth of souls is great in the sight of God;
11. For, behold, the Lord your Redeemer suffered death in the flesh; wherefore he suffered the pain of all men, that all men might repent and come unto him.
12. And he hath risen again from the dead, that he might bring all men unto him, on conditions of repentance.
13. And how great is his joy in the soul that repenteth!
14. Wherefore, you are called to cry repentance unto this people.
15. And if it so be that you should labor all your days in crying repentance unto this people, and bring, save it be one soul unto me, how great shall be your joy with him in the kingdom of my Father!
16. And now, if your joy will be great with one soul that you have brought unto me in the kingdom of my Father, how great will be your joy if you should bring many souls unto me!

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.

Alma 26:22

22. Yea, he that repenteth and exerciseth faith, and bringeth forth good works, and prayeth continually without ceasing -- unto such it is given to know the mysteries of God; yea, unto such it shall be given to reveal things which never have been revealed; yea, and it shall be given unto such to bring thousands of souls to repentance, even as it has been given unto us to bring these our brethren to repentance.

Enos 1:3-8

3. Behold, I went to hunt beasts in the forests; and the words which I had often heard my father speak concerning eternal life, and the joy of the saints, sunk deep into my heart.
4. And my soul hungered; and I kneeled down before my Maker, and I cried unto him in mighty prayer and supplication for mine own soul; and all the day long did I cry unto him; yea, and when the night came I did still raise my voice high that it reached the heavens.
5. And there came a voice unto me, saying: Enos, thy sins are forgiven thee, and thou shalt be blessed.
6. And I, Enos, knew that God could not lie; wherefore, my guilt was swept away.
7. And I said: Lord, how is it done?
8. And he said unto me: Because of thy faith in Christ, whom thou hast never before heard nor seen. And many years pass away before he shall manifest himself in the flesh; wherefore, go to, thy faith hath made thee whole.

Alma 5:19

19. I say unto you, can ye look up to God at that day with a pure heart and clean hands? I say unto you, can ye look up having the image of God engraven upon your countenances?

2 Nephi 31:13

13. Wherefore, my beloved brethren, I know that if ye shall follow the Son, with full purpose of heart, acting no hypocricy and no deception before God, but with real intent, repenting of your sins, witnessing unto the Father that you are willing to take upon you the name of Christ, by baptism-yea, by following your Lord and your Savior down into the water, according to his word, behold, then shall ye receive the Holy Ghost, yea, then cometh the baptism of fire and of the Holy Ghost; and then can ye speak with the tongue of angels, and shout praises unto the Holy One of Israel.

D&C 19:16-19

16. For behold, I God have suffered these things for all, that they might not suffer if they would repent.
17. But if they would not repent they must suffer even as I.
18. Which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit; and would that I might not drink the bitter cup and shrink;
19. Nevertheless, glory be to the Father, and I partook and finished my preparations unto the children of men.
