If you believe in freedom of religion, then why do you need to ask me that? Why do you feel such a moral superiority? Unbelievable.
I believe in freedom of religion, just as I believe in free will that God grants all of us.
The reason I ask you that has nothing to do with wanting to restrict your freedom of religion or free will, it has to do with asking you why you would believe in a book that contradicts the Holy Word of God?
You cannot say you believe in the Bible as God’s Holy (and sealed) Covenant that He died on the Cross for us for, and then say BUT it is okay to add a whole new appendix to that “outdated” Word.
That reasoning contradicts the Bible itself.
So, what is the harm, then for you to not put your trust in the Book of Mormon but simply and Scripturally, just in the Word of God?
