“Thank you for pointing out that Mormons use the King James version of the Bible.”
They use the KJV to suck in the unsuspecting. Then they take it away and give them the book of Mormon.
Unfortunately, you're right. Maybe if Mormons would just stop with the KJV instead of adding all the man-made drivel like the Book of Mormon and the rest, they'd get saved and become true Christians, instead of those who merely claim the name.
