The bible tell us there will be prophets, but since you fail to read the context within prophets work within the NT era today, suffice it to say that your definition of a prophet is different from Biblical definitions.
Showing them scripture doesn’t mean anything to a Mormon. They don’t believe in the Bible. Their Bible is the BOM ONLY...NOT the KJV as they pretend.
Funny how the Bible is only used to show ERROR but the BOM is infallable!
