The prophecies in these chapters are beautiful. They feel good. Towards the end of this chapter, Nephi is told that he shall not write the remainder of the things which he has seen, but that one of the Apostles of the Lamb of God shall write them. Hopefully this sounds familiar, but if not, verse 27 leaves no room to err. The Apostle's name would be John. Let me think for a moment, where was it again that I've read about the end of the world and the events preceding Christ's second coming? I believe that would be the Book of Revelation, written by the Apostle John.
Let us also reflect on some of the teachings of the preceding chapters - that many of the plain and precious truths and covenants contained in the record of the Jews (Bible) would be lost.
So - for events concerning the end of the world, we turn to the Bible. For a more clear and all-encompassing collection of the doctrines of Christ's Gospel (faith, repentance, baptism, Holy Ghost, endure...), we turn to the Book of Mormon. For a more detailed description of the life of Christ, we turn to the Bible. For a second testament of His life, we open the Book of Mormon. And so on, and so forth.
What I mean to suggest by all this is that BOTH are very desirable. Both have much to offer us. We need these two testimonies as one in our hands, as prophesied would be the case in Ezekiel 37:15-17. One supports the other. What a blessing to have such access to the precious word of God. May we all be overcome with gratitude in so much that we take advantage of these wonderful blessings.
