One of the doctrines which most distinguishes Mormons from Christians is their belief that God was once a human being, just as you and I now are, but on another planet, ruled by its own deity. Their General Authority Milton Hunter (The Gospel Through the Ages, 1945, p. 104) wrote, "Mormon prophets have continuously taught the sublime truth that God the Eternal Father was once a mortal man who passed through a school of earth life similar to that through which we are now passing." This is one of the doctrines that the boys on the bicycles do not explain to prospective converts. It is kept until the person has been involved for a while.
In contrast, Christians profess, together with Moses (Psalm 90:2), "Even from everlasting to everlasting, You are God." The God of the Bible has always been God, from eternity past, and always will be God, into eternity future.
So, we have a contrast here between an evolutionary view of a god, in opposition to a view of a God who is eternal. Does the Bible say anything else applicable to this question?
In Numbers 23:19, Moses also said, "God is not man, that He should lie, or a son of man, that He should
change His mind. Has He said, and will He not do it? Or has He spoken,
and will He not fulfill it?" If God doesn't change His mind, are we to believe that He changes His nature?
In I Samuel 15:29, we read, "The Glory of Israel will not lie or have regret, for He is not a man." God is not a man (this does not address the incarnation of Christ)! He is not a man now, a Mormon might respond. Okay.
In Malachi 3:6, God speaks for Himself: "I am the Lord , I do not change." We can also look at Isaiah 43:10: "Before Me no god was formed, nor shall there be any after Me." The first prophet tells us that God could never have been anything other that what He now is. The second tells us that there could never have been an earlier deity under whom our God attained His divine status. I have dealt more with the verses in Isaiah here.
I am writing this the way I am, because I have run into too many Mormons who complain when I or anyone else says that they are not Christians. First, this is the height of hypocrisy, since those same boys on bicycles are traveling around telling prospects that all other professing Christians are apostates. Did you catch that? All! Second, I know that most people aren't aware of some of the more-bizarre doctrines of the Mormons, so they are also not aware of how un-Christian they really are. I aim, in part, to educate those folks. I also intend to provide them with the truth, so that they have an answer to give both the boys on bicycles and to their Mormon neighbors (I Peter 3:15).
