Here, Mormon is writing his last words in the Book of Mormon, we hear more from him later but that is Moroni sharing the words of his father. Really Mormon chapter 7 is Mormon's goodbye, and in it he provides us with a beautiful bookend to the words he wrote in the Title Page of the Book of Mormon by echoing the purposes of the Book of Mormon that we find there. But then Mormon helps us see that in the coming forth of the Book of Mormon, Heavenly Father invokes the law of the witnesses to testify that Jesus is the Christ.
