You have no idea what you are talking about. You have swallowed a little truth, along with a whole lot of lies. Go ahead and preach. Nothing you say can affect my relationship with the Savior. You have no idea what Mormons believe about Christ.
What would that be lady?
If you have a true relationship with Jesus, you would understand that you cannot add to the Word any other Gospel. He is revealed through that Eternal Word that will “never pass away”...
... because He is the Word made Flesh. For your own sake, don’t dilute or distort who you worship with diverse and strange ideas that are not His.
