Here is the definition of our hope. Hope looks to the post-mortal, and specifically to our perfection in Christ. That does not happen in this mortality, but rather in our experiences after this world. To accomplish this perfection and to receive the blessings that will come through it, we must accept Jesus Christ. Moroni ends with this defining purpose of the whole of the text that his father wrote, and the whole of his interest in preserving and delivering that text. The Book of Mormon is truly another witness for Christ, not to his reality, but to his divinity.
