Genesis 1:1-5 vs Abraham 4:1-5 (God vs Gods)

Genesis 1:1-5 KJV
1 In the beginning God created the heaven and the earth.
2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
3. And God said, Let there be light: and there was light.
4 And God saw the light, that it was good: and God divided the light from the darkness.
5 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

Vs

Abraham 4:1-5
1 And then the Lord said: Let us go down. And they went down at the beginning, and they, that is the Gods, organized and formed the heavens and the earth.
2 And the earth, after it was formed, was empty and desolate, because they had not formed anything but the earth; and darkness reigned upon the face of the deep, and the Spirit of the Gods was brooding upon the face of the waters.
3 And they (the Gods) said: Let there be light; and there was light.
4 And they (the Gods) comprehended the light, for it was bright; and they divided the light, or caused it to be divided, from the darkness.
5 And the Gods called the light Day, and the darkness they called Night. And it came to pass that from the evening until morning they called night; and from the morning until the evening they called day; and this was the first, or the beginning, of that which they called day and night.

Mormons who believe the Book of Abraham are denying what is written in Genesis. They are accepting a belief in a plurality of Gods instead of a one true God which the Bible teaches. As for Joseph Smith, who wrote this false Book of Abraham, there is a warning when it comes to tampering with the Word of God. I am speaking of the plagues mentioned in Revelation.

Revelation 22:18-19 KJV
18 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:
19 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.
