“There’s a lot of born-again Christians in this world who are nevertheless deceived. None of us have got it all right. And some are way off. But, “He that comes to Me I will in no way cast him out.” The blood of Jesus is effectual to cover all our sins and errors and to “save to the uttermost.””
If a “deceived” born again Christian, of which there are millions, nevertheless believes in Jesus Christ, they are saved. Mormons deny the Jesus of the Bible and replace Him with an absurd, blasphemous counterpart that not only did not die to save them, but is just another “spirit brother” pointing the way to a lifetime of secret handshakes and temple rituals that MIGHT get you in to the celestial heaven where you can become a god. If you’re a woman, well, you better hope you’re married to a Mormon. There’s no individual path to heaven for you outside of that! And if you FAIL as a man, well, you’ll get into one of the lesser heavens where you can’t become a god. No Mormon who believes Mormon theology can ever get into heaven.
Again, the argument here is that we are saved by grace, not by works. The irony in this discussion is that Mormonism is all about works, not about salvation by grace only. And yet some Christians argue that because a born-again Christian might be a member of the Mormon Church, he must not be saved. So his work of being in the wrong church or doing the wrong thing keeps him from salvation. That’s a Mormon-esque works-based argument for salvation, not a Biblical one.
