All empirical evidence points to its fraudulent origins. Joseph Smith was a fraud too. But I won't bother going into the details on this thread. Suffice it to say that I am as convinced that the Book of Mormon is a fraud as you are convinced that it is the truth.
But I have placed my faith and trust solely in Jesus Christ, and on that measure, I believe that I am saved.
It is good to know that you would still have "faith in Christ" if the Book of Mormon were proven (to you) to be a fraud.
Do you believe that your salvation is in any way contingent upon accepting the truth of the Book of Mormon or the Prophetic calling of Joseph Smith?
If you only believed in the Christ revealed in the New Testament and your faith was not tied to any church or any other person or any modern scriptures, but only in the Lord Jesus Christ, do you believe that you would be saved?
There is a difference between salvation and exaltation. Salvation from the grave was a free gift of the Savior to all. Had His sacrifice not happened on the cross and in the Garden of Gethsemane, none of us would ever had left the grave after we died. We will all leave the grave, thanks to Him. But what happens after we leave the grave is due in part to our works, overlaid with a huge measure of mercy and grace. There is not just one level of heaven but many. Christ said His Father’s house has many mansions. The “mansion” to which we go will depend on the type of person we became here on earth. We will, to put it in simple terms, go to a place where the people are just like us. If we are good, then our place/mansion will be good. If we are evil, then it will be evil.
My salvation is assured. My exaltation depends on my seeking out the truth and living in accordance with that truth. Our faith has a different understanding of Hell. It is a sparsely-populated place without light of any kind and is also known as Outer Darkness but only those who absolutely know the Savior as in face to face revelation and visitation and then renounce Him will go to Outer Darkness. All others will have different degrees of exaltation, although as I said, you and your similar neighbors will determine whether it is a heavenly or hellish place to dwell forever.
I respect your opinion and I wouldn’t try to convince you otherwise. I know you are concerned for my salvation. I just know what I know beyond a shadow of a doubt and I will trust to the Savior for my salvation and exaltation. He is my Redeemer and my Savior, the Only Begotten of the Father, the Way, the Light, the Life, and the Bread and Water of Eternal Life. And I came to know and appreciate it so much more through the Book of Mormon. I don’t expect you to understand that and I do appreciate your sincerity and zeal for the truth. God bless.
