There is an interesting scripture in the book of Moses. It reads, "Wherefore, because that Satan rebelled against me, and sought to destroy the agency of man, which I, the Lord God, had given him, and also, that I should give unto him mine own power; by the power of mine Only Begotten, I caused that he should be cast down; And he became Satan, yea, even the devil, the father of all lies, to deceive and to blind men, and to lead them captive at his will, even as many as would not hearken unto my voice." (Moses 4: 3-4). The interesting thing is Satan is called "the father of all lies"; he could have been called many other things (and he can be called many things) but the Lord chose to call him the father of all lies. Satan's self-proclaimed work is to deceive and blind men and lead them down to captivity, pawns to his will and whims. All lies come from Satan; he is their creator. Those who lie preach the devil's gospel and spread his bad word. Those who are dishonest become Satan's children. Is not it better to become sons and daughters of God?
Continuing on in Moses 4 we read the following (I will add some commentary in brackets):
"6 And Satan put it into the heart of the serpent, (for he had drawn away many after him,) and he sought also to beguile Eve, for he knew not the mind of God, wherefore he sought to destroy the world. [Satan thought his lying to Eve would frustrate God's plan when in fact it furthered God's plan].Satan tried to lie to Eve. He tried to destroy God's plan but he didn't know that he was actually furthering God's plan; what Satan did was without authority or permission but Adam and Eve partaking of the fruit was part of God's plan - whether they eventually partook of it by themselves, or someone else gave it to them. In any case, when Satan realized that he was cursed for what he had done (he already was cursed but in this case he was upset he had not actually frustrated God's plans but furthered them). Satan became very angry and has been ever since. He rages against God and all of us. He tries to cause the nations to rage furiously together, brother against brother, father against son, daughter against mother, neighbor against neighbor, and people against people. I do not believe that Satan is so angry that He cannot think properly - to the contrary, he thinks very clearly - but he is angry because of what he lost and angry at us mortals on earth who have opportunities for progression he will never have. And so Satan lies and deceives and encourages dishonesty in others. He knows that when we are dishonest we are not godlike or godly. He knows the pain and suffering lies cause and so he encourages them and laughs at the suffering of others. He rejoices in our failures and sins and sorrows. God does not.
7 And he said unto the woman: Yea, hath God said—Ye shall not eat of every tree of the garden? (And he spake by the mouth of the serpent.)
8 And the woman said unto the serpent: We may eat of the fruit of the trees of the garden;
9 But of the fruit of the tree which thou beholdest in the midst of the garden, God hath said—Ye shall not eat of it, neither shall ye touch it, lest ye die.
10 And the serpent said unto the woman: Ye shall not surely die; [a lie].
11 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil. [This is true].
12 And when the woman saw that the tree was good for food, and that it became pleasant to the eyes, and a tree to be desired to make her wise, she took of the fruit thereof, and did eat, and also gave unto her husband with her, and he did eat.
13 And the eyes of them both were opened, and they knew that they had been naked. And they sewed fig-leaves together and made themselves aprons.
14 And they heard the voice of the Lord God, as they were walking in the garden, in the cool of the day; and Adam and his wife went to hide themselves from the presence of the Lord God amongst the trees of the garden.
15 And I, the Lord God, called unto Adam, and said unto him: Where goest thou?
16 And he said: I heard thy voice in the garden, and I was afraid, because I beheld that I was naked, and I hid myself.
17 And I, the Lord God, said unto Adam: Who told thee thou wast naked? Hast thou eaten of the tree whereof I commanded thee that thou shouldst not eat, if so thou shouldst surely die?
18 And the man said: The woman thou gavest me, and commandest that she should remain with me, she gave me of the fruit of the tree and I did eat.
19 And I, the Lord God, said unto the woman: What is this thing which thou hast done? And the woman said: The serpent beguiled me, and I did eat.
20 And I, the Lord God, said unto the serpent: Because thou hast done this thou shalt be cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life;
21 And I will put enmity between thee and the woman, between thy seed and her seed; and he shall [crush] thy head, and thou shalt bruise his heel." (Moses 4:6-21).
