The Bible says that there is ONLY ONE GOD (Deuteronomy 6:4).
However, section 132 of Doctrine and Covenants says that "men may become gods".
So which is correct?
Well, section 132 of Doctrine and Covenants was written later when Smith wanted to teach Mormons to marry multiple wives. Here he added that in the next life those who followed this new covenant would become gods: "Then shall they be gods, because they have all power, and the angels are subject unto them." Doctrine and Covenants 132:20.
And what does God say will happen to those who would add to His word or take away from it...
"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
"ADD thou not unto his words, lest he reprove thee, and thou be found a liar." -Proverb 30:6
Many people today question the Bible's veracity. Do you honestly believe that God does not have the power to preserve His Word from a wicked generation?
"The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times. Thou shalt keep them, O LORD, THOU SHALT PRESERVE THEM FROM THIS GENERATION FOR EVER." -Psalm 12:6,7
Know ye not that the word of God endureth forever? Where do you think the word of God was before false prophet Joseph Smith came along? Hidden? Nay, it cannot be destroyed!
"For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: 1:25 But THE WORD OF THE LORD ENDURETH FOR EVER. And this is the word which by the gospel is preached unto you." -1st Peter 1:24
So which is correct? The answer is the Bible.
Joseph Smith added to God‘s word; thus, he was a liar.
You see, if the teachings of the Mormonism are correct now, then they were clearly wrong from 1830 until about 1842 when they thought that there was only one God and that God was not once a man. But if they were correct from 1830 to about 1842, then they are wrong now because Mormon doctrine says that there are many gods (Doctrine and Covenants 132) and that God progressed from once being a man.
But from 1 Corinthians 14:33 we learn, "For God is not the author of confusion, but of peace, as in all churches of the saints." This confusion of Mormon doctrine should make any thinking person wonder about the reliability of the rest of it's teachings.
So then how can you know for sure that you are saved?
The Bible says that salvation is by grace through faith in Jesus Christ and not of works. There is no amount of good works or ceremonies that you can do to save your soul because salvation is a gift.
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast” Ephesians 2:8-9
I’ll say it again, salvation is a gift available for all who simply believe in Jesus Christ. Salvation is sure because it is a gift. Whereas, if it is a matter of works, then no one can be sure of being saved.
We see in Acts 16:30-31 where the jailer asked Paul and Silas, “Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.”
Believe on the Lord Jesus Christ alone and you will without a shadow of a doubt be saved.
“These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life...” 1 John 5:13
