>>Simple question- How does the Book of Mormon square with
>>the final statement in Revelations?
A simple answer: Who cares? The book of Deuteronomy ends with a similar warning. The book of revelations was written before many of the other gospels, do we throw them out too? Books of scripture were separate books. (Kind of like the Nancy Drew series.) They were separate until compiled into a collection or Biblia (See http://www.newadvent.org/cathen/02543a.htm) The order they were placed in was subject to debate, until a logical solution was reached (Revelations was last because no one understood it.)
Um, Does that answer your question?
A simple correction.
Anybody who is a believer in God through faith in Christ by the plan of God the Father established in eternity past would pay heed to the admonishment at the end of the Revelation of our Lord and Savior Christ Jesus as communicated to His disciple John by His angel.
Interesting point that you bring up,..do you really mean to imply Joseph Smith lied when he claimed to come face to face with the Father and the Son, which would be in contradiction to the last few verses in Deuteronomy?
