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 3:5-10, 17, 19

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 the 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.
9 And lo, he cometh unto his own, that salvation might come unto the children of men even through faith on his name; and even after all this they shall consider him a man, and say that he hath a devil, and shall scourge him, and shall crucify him.
10 And he shall arise the third day from the dead; and behold, he standeth to judge the world; and behold, all these things are done that a righteous judgment might come upon the children of men.

17 And moreover, I say unto you, that there shall be no other name given nor any other way nor means whereby salvation can come unto the children of men, only in and through the name Christ, the Lord Omnipotent.

19 For the natural man is an enemy to God, and has been from the fall of Adam, and will be, forever and ever, unless he yields to the enticings of the Holy Spirit, and putteth off the natural man and becometh a saint through the atonement of Christ the Lord, and becometh as a child, submissive, meek, humble, patient, full of love, willing to submit to all things which the Lord seeth fit to inflict upon him, even as a child doth submit to his father.

Mosiah 3:19

19. For the natural man is an enemy to God, and has been from the fall of Adam, and will be, forever and ever, unless he yields to the enticings of the Holy Spirit, and putteth off the natural man and becometh a saint through the atonement of Christ the Lord, and becometh as a child, submissive, meek, humble, patient, full of love, willing to submit to all things which the Lord seeth fit to inflict upon him, even as a child doth submit to his father.

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.

Moses 5:11

11. And Eve, his wife, heard all these things and was glad saying; were it not for our transgression, we never should have had seed, and never should have known good and evil, and the joy of our redemption, and the eternal life which God giveth unto all the obedient.

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.
