Info to help you decide if you will believe the Bible or JOSEPH SMITH & The Book of Mormon / The Church of Jesus Christ of Latter-day Saints

Although Mormons are usually friendly, loving, and kind people, they are deceived by a false religion that distorts the nature of God, the Person of Jesus Christ, and the means of salvation…

First of all – is it salvation issue? Yes. They add what we can do to grace ( which is a FREE gift of UNDESERVED KINDNESS ). 

We can no add works to it…yet the LDS church says it “may” come as a result after us doing “all that we can do”.
The problem with Mormonism is that it contradicts, modifies, and expands on the Bible….
Mormonism teaches that salvation can be earned by a combination of faith and good works (LDS Bible Dictionary, p. 697).

…Yes, works alone cannot bring that divine gift, but they are a key condition upon which the gift is received. (See 2 Ne. 10:23–25.) “For we know that it is by grace that we are saved, after all we can do.” (2 Ne. 25:23.)
Thus, unless one has done all in his own power, he cannot expect the grace of God to be manifest. What a glorious principle to understand: the Lord’s assistance to us—whether we have strong faith or weak faith; whether a man, a woman, or a child—is not based just on what we know, how strong we are, or who we are, but more upon our giving all that we can give and doing all that we can do in our present circumstance. Once one has given all he can, then the Lord, through His grace, may assist him. (See D&C 123:17.)

AND ALSO :
Mormonism adds words to Genesis, adds other books, and has failed prophecies as well as errors created in the additions Josephy Smith made to Genesis.
From GotQuestions: The Mormon religion (Mormonism), whose followers are known as Mormons and Latter-day Saints (LDS), was founded less than two hundred years ago by a man named Joseph Smith.
He claimed to have received a personal visit from God the Father and Jesus Christ (Articles of Faith, p. 35) who told him that all churches and their creeds were an abomination (1 Nephi 13:28; Pearl of Great Price, Joseph Smith – History 1:18, 19).
Joseph Smith then set out to “restore true Christianity” and claimed his church to be the “only true church on earth” (Mormon Doctrine, p. 670; 1 Nephi 14:10).

Genesis in KJV has only 26 chapters. 

Here are the last chapters : KJV in blue and the LDS scriptures in purple

And Joseph said unto his brethren, I die: and God will surely visit you, and bring you out of this land unto the land which he sware to Abraham, to Isaac, and to Jacob. And Joseph took an oath of the children of Israel, saying, God will surely visit you, and ye shall carry up my bones from hence. So Joseph died, [being] an hundred and ten years old: and they embalmed him, and he was put in a coffin in Egypt. [Gen 50:24-26 KJV]

LDS says : Joseph in Egypt prophesies of Moses freeing Israel from Egyptian bondage; of a branch of Joseph’s descendants being led to a faraway land, where they will be remembered in the covenants of the Lord; of God calling a latter-day prophet named Joseph to join the records of Judah and of Joseph; and of Aaron serving as a spokesman for Moses.

24 And Joseph said unto his brethren, I die, and go unto my fathers; and I go down to my grave with joy. The God of my father Jacob be with you, to deliver you out of affliction in the days of your bondage; for the Lord hath visited me, and I have obtained a promise of the Lord, that out of the fruit of my loins, the Lord God will raise up a righteous branch out of my loins; and unto thee, whom my father Jacob hath named Israel, a prophet; (not the Messiah who is called Shilo;) and this prophet shall deliver my people out of Egypt in the days of thy bondage.

25 And it shall come to pass that they shall be scattered again; and a branch shall be broken off, and shall be carried into a far country; nevertheless they shall be remembered in the covenants of the Lord, when the Messiah cometh; for he shall be made manifest unto them in the latter days, in the Spirit of power; and shall bring them out of darkness into light; out of hidden darkness, and out of captivity unto freedom.

26 A seer shall the Lord my God raise up, who shall be a choice seer unto the fruit of my loins.

27 Thus saith the Lord God of my fathers unto me, A choice seer will I raise up out of the fruit of thy loins, and he shall be esteemed highly among the fruit of thy loins; and unto him will I give commandment that he shall do a work for the fruit of thy loins, his brethren.

28 And he shall bring them to the knowledge of the covenants which I have made with thy fathers; and he shall do whatsoever work I shall command him.

29 And I will make him great in mine eyes, for he shall do my work; and he shall be great like unto him whom I have said I would raise up unto you, to deliver my people, O house of Israel, out of the land of Egypt; for a seer will I raise up to deliver my people out of the land of Egypt; and he shall be called Moses. And by this name he shall know that he is of thy house; for he shall be nursed by the king’s daughter, and shall be called her son.

30 And again, a seer will I raise up out of the fruit of thy loins, and unto him will I give power to bring forth my word unto the seed of thy loins; and not to the bringing forth of my word only, saith the Lord, but to the convincing them of my word, which shall have already gone forth among them in the last days;

31 Wherefore the fruit of thy loins shall write, and the fruit of the loins of Judah shall write; and that which shall be written by the fruit of thy loins, and also that which shall be written by the fruit of the loins of Judah, shall grow together unto the confounding of false doctrines, and laying down of contentions, and establishing peace among the fruit of thy loins, and bringing them to a knowledge of their fathers in the latter days; and also to the knowledge of my covenants, saith the Lord.

32 And out of weakness shall he be made strong, in that day when my work shall go forth among all my people, which shall restore them, who are of the house of Israel, in the last days.

33 And that seer will I bless, and they that seek to destroy him shall be confounded; for this promise I give unto you; for I will remember you from generation to generation; and his name shall be called Joseph, and it shall be after the name of his father; and he shall be like unto you; for the thing which the Lord shall bring forth by his hand shall bring my people unto salvation.

34 And the Lord sware unto Joseph that he would preserve his seed forever, saying, I will raise up Moses, and a rod shall be in his hand, and he shall gather together my people, and he shall lead them as a flock, and he shall smite the waters of the Red Sea with his rod.

KJV MOSES DID NOT SMITE THE WATERS: 

But lift thou up thy rod, and stretch out thine hand over the sea, and divide it: and the children of Israel shall go on dry [ground] through the midst of the sea. … And Moses stretched out his hand over the sea; and the LORD caused the sea to go [back] by a strong east wind all that night, and made the sea dry [land], and the waters were divided. [Exo 14:16, 21 KJV]

35 And he shall have judgment, and shall write the word of the Lord. And he shall not speak many words, for I will write unto him my law by the finger of mine own hand. And I will make a spokesman for him, and his name shall be called Aaron.

36 And it shall be done unto thee in the last days also, even as I have sworn. Therefore, Joseph said unto his brethren, God will surely visit you, and bring you out of this land, unto the land which he sware unto Abraham, and unto Isaac, and to Jacob.

37 And Joseph confirmed many other things unto his brethren, and took an oath of the children of Israel, saying unto them, God will surely visit you, and ye shall carry up my bones from hence.

38 So Joseph died when he was an hundred and ten years old; and they embalmed him, and they put him in a coffin in Egypt; and he was kept from burial by the children of Israel, that he might be carried up and laid in the sepulchre with his father. And thus they remembered the oath which they sware unto him.

Why don’t we call ourselves Mormons?
The term “Mormons” is a nickname that comes from a book of scripture unique to our Church called the Book of Mormon. We didn’t come up with the nickname, but lots of people use it to describe the Church and its members. In the past, we’ve embraced the term and even used it ourselves, but recently we have asked people to call the Church by its full name: The Church of Jesus Christ of Latter-day Saints. This re-emphasis of the Church’s name helps us follow the Lord’s command given to the prophet Joseph Smith: “For thus shall my church be called in the last days, even The Church of Jesus Christ of Latter-day Saints” (Doctrine and Covenants 115:4). It also helps everyone know that Jesus is the core of our religion and beliefs.
“Latter-day Saints” is a good way to refer to your friends who are members of the Church.

But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die. And if thou say in thine heart, How shall we know the word which the LORD hath not spoken? When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that [is] the thing which the LORD hath not spoken, [but] the prophet hath spoken it presumptuously: thou shalt not be afraid of him. [Deuteronomy 18:20-22 KJV]

For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and [from] the things which are written in this book. [Revelation 22:18-19 KJV]
