Mormons teach that man can rise to the challenge in this life and so become their own god of their own world in the next life.
“Abraham received concubines, and they bore him children; and it was accounted unto him for righteousness, because they were given unto him, and he abode in my law; as Isaac also and Jacob did none other things than that which they were commanded; and because they did none other things than that which they were commanded, they have entered into their exaltation, according to the promises, and sit upon thrones, and are not angels but are gods.”
Doctrine and Covenants (D&C) 132:37
“A time to come in the which nothing shall be withheld, whether there be one God or many gods, they shall be manifest.”
“According to that which was ordained in the midst of the Council of the Eternal God of all other gods before this world was, that should be reserved unto the finishing and the end thereof, when every man shall enter into his eternal presence and into his immortal rest.”
These texts conflict with the Bible being God declares that there are no other gods, will be no other gods and that He does not share His glory (See Isaiah 46:9, “for I am God, and there is no other; I am God, and there is none like me”). In heaven, at the end of the age, those who are saved are said to be made priests and kings of the one God only, never gods (Rev. 5:9-10).
If there is a plurality of gods out there (men becoming gods of their own worlds) why does the God of the Bible not know of them? (Isaiah 43:10, “Before me no god was formed, nor shall there be any after me.”). Again, just some noted differences between LDS and actual Christian teaching.
