Do you accept the Book of Mormon as fact? If so, then you in fact reject Scripture.
You’re free to follow your heart. As for me, I’ll reject Joseph Smith and follow Christ.
I follow Christ and Joseph Smith. We can play semantics with words, but why bother?
Jesus Christ is my Savior and Redeemer. Joseph Smith was a Prophet of the Savior.
So for you to try to define my heart is a futile attempt because you don’t know my heart or mind. Moreover, you don’t know my relationship with Christ. Jesus loves us both. See John 3:16 for further details.
I accept the Book of Mormon on faith. Ever heard of that term?
