D&C 122:5-8

5. If thou art called to pass through tribulation; if thou art in perils among false brethren; if thou art in perils among robbers; if thou art in perils by land or by sea;
6. If thou art accused with all manner of false accusations; if thine enemies fall upon thee; if they tear thee from the society of thy father and mother and brethren and sisters; and if with a drawn sword thine enemies tear thee from the bosom of thy wife, and of thine offspring, and thine elder son, although but six years of age, shall cling to thy garments, and shall say, My father, my father, why can't you stay with us? O, my father, what are the men going to do with you? and if then he shall be thrust from thee by the sword, and thou be dragged to prison, and thine enemies prowl around thee like wolves for the blood of the lamb;
7. And if thou shouldst be cast into the pit, or into the hands of murderers, and the sentence of death be passed upon thee; if thou be cast into the deep; if the billowing surge conspire against thee; if fierce winds become thine enemy; if the heavens gather blackness, and all the elements combine to hedge up the way; and above all, if the very jaws of hell shall gape open the mouth wide after thee, know thou, my son, that all these things shall give thee experience, and shall be for thy good.
8. The Son of Man hath descended below them all. Art thou greater than he?

D&C 14:7

7. And, if ye keep my commandments and endure to the end ye shall have eternal life, which gift is the greatest of all the gifts of God.

Gordon B. Hinckley (April 1995 Conference)

This church does not belong to its President. Its head is the Lord Jesus Christ, whose name each of us has taken upon ourselves. We are all in this great endeavor together. We are here to assist our Father in His work and His glory, "to bring to pass the immortality and eternal life of man." (Moses 1:39) Your obligation is as serious in your sphere of responsibility as is my obligation in my sphere. No calling in this church is small or of little significance. All of us in the pursuit of our duty touch the lives of others...

You have as great an opportunity for satisfaction in the performance of your duty as I do in mine. The progress of this work will be determined by our joint efforts. Whatever your calling, it is fraught with the same kind of opportunity to accomplish good as is mine. What is really important is that this is the work of the Master. Our work is to go about doing good as did He.

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.

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.

Bible Dictionary - Prayer

As soon as we learn the true relationship in which we stand toward God (namely, God is our Father, and we are his children) then at once prayer becomes natural and instinctive on our part. Many of the so-called difficulties about prayer arise from forgetting this relationship. Prayer is the act by which the will of the Father and the will of the child are brought into correspondence with each other. The object of prayer is not to change the will of God, but to secure for ourselves and for others blessings that God is already willing to grant, but that are made conditional on our asking for them. Blessings require some work or effort on our part before we can obtain them. Prayer is a form of work, and is an appointed means for obtaining the highest of all blessings...

Christians are taught to pray in Christ's name. We pray in Christ's name when our mind is the mind of Christ, and our wishes the wishes of Christ-when his words abide in us. Many prayers remain unanswered because they are not in Christ's name at all; they in no way represent his mind, but spring out of the selfishness of man's heart.

Matthew 6:5-13

5. And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, they have their reward.
6. But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
7. But when ye pray, use not vain repetitions as the heathen do: for they think that they shall be heard for their much speaking.
8. Be ye not therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him.
9. After this manner therefore pray ye: Our Father which art in Heaven, Hallowed be thy name.
10. Thy kingdom come. Thy will be done in earth, as it is in heaven.
11. Give us this day our daily bread.
12. And forgive us our debts, as we forgive our debtors.
13. And lead us not into temptation, but deliver us from evil: for thine is the kingdom, and the power, and the glory, for ever. Amen.
