Mosiah 5:2, 7, 13

2 And they all cried with one voice, saying: Yea, we believe all the words which thou hast spoken unto us; and also, we know of their surety and truth, because of the Spirit of the Lord Omnipotent, which has wrought a mighty change in us, or in our hearts, that we have no more disposition to do evil, but to do good continually.

7 And now, because of the covenant which ye have made ye shall be called the children of Christ, his sons, and his daughters; for behold, this day he hath spiritually begotten you; for ye say your hearts are changed through faith on his name; therefore, ye are born of him and have become his sons and his daughters.

13 For how knoweth a man the master whom he has not served, and who is a stranger unto him, and is far from the thoughts and intents of his heart.

Jacob 5:35

35 And it came to pass that the Lord of the vineyard said unto his servant: The tree profiteth me nothing, and the roots of the tree profit me nothing so long as it shall bring forth evil fruit.

2 Nephi 11:4-5

4. Behold, my soul delighteth in proving unto my people of the coming of Christ; for, for this intent hath the law of Moses been given, and all things which hath been given of God from the beginning of the world, unto man, are the typifying of him.
5. And also my soul delighteth in the covenants of the Lord which he hath made to our fathers; yea, my soul delighteth in his grace, and in his justice, and power, and mercy, in the great and eternal plan of deliverance from death.

2 Nephi 8:6-7

6. Lift up your eyes to the heavens, and look upon the earth beneath; for the heavens shall vanish away like smoke, and the earth shall wax old like a garment; and they that dwell therein shall die in like manner. But my salvation shall be forever, and my righteousness shall not be abolished.
7. Hearken unto me, ye that know righteousness, the people in whose heart I have written my law, fear ye not the reproach of men, neither be ye afraid of their revilings.

Jeremiah 20:9

9. Then I said, I will not make mention of him, nor speak in his name anymore. But his word was in mine heart as a burning fire shut up in my bones, and I was weary with forebearing, and I could not stay.

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.

Helaman 3:35

35. Nevertheless they did fast and pray oft, and did wax stronger and stronger in their humility, and firmer and firmer in the faith of Christ, unto the filling their souls with joy and consolation, yea, even to the purifying and sanctification of their hearts, which sanctification cometh because of their yielding their hearts unto God.

Robert D. Hales (Oct 2007 Conference)

By design, most miracles are spiritual demonstrations of God's power--tender mercies gently bestowed through impressions, ideas, feelings of assurance, solutions to problems, strength to meet challenges, and comfort to bear disappointments and sorrow.

John 13:34-35

34. A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
35. By this shall all men know that ye are my disciples, if ye have love one to another.

David O. McKay (at BYU April 27, 1948)

There is one responsibility which no man can evade; that responsibility is his personal influence. Man's unconscious influence is the silent, subtle radiation of personality--the effect of his words and his actions on others. This radiation is tremendous. Every moment of life man is changing, to a degree, the life of the whole world.

Every man has an atmosphere which is affecting every other man. He cannot escape for one moment from his radiation of his character, this constant weakening or strengthening of others. Man cannot evade the responsibility by merely saying that it is an unconscious influence.

Man can select the qualities he would permit to be radiated. He can cultivate sweetness, calmness, trust, generosity, truth, justice, loyalty, nobility and make them vitally active in his character. And by these qualities he will constantly affect the world.

This radiation, to which I refer, comes from what a person really is, not from what he pretends to be. Every man by his mere living is radiating either sympathy, sorrow, morbidness, cynicism, or happiness and hope or any one of a hundred other qualities.

Life is a state of radiation and absorption. To exist is to radiate; to exist is to be the recipient of radiation.

Dallin H. Oaks (October 2000 Conference)

The Final Judgment is not just an evaluation of a sum total of good and evil acts-what we have done. It is an acknowledgment of the final effect of our acts and thoughts-what we have become. It is not enough for anyone just to go through the motions. The commandments, ordinances, and covenants of the gospel are not a list of deposits required to be made in some heavenly account. The gospel of Jesus Christ is a plan that shows us how to become what our Heavenly Father desires us to become.

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.
