The chapters in the Book of Mormon up til about chapter 11 are not very happy.
And yet Mormon, always the optimist, finds a way to put a positive spin on things.
In 3 Nephi 5:13, "Behold, I am a disciple of Jesus Christ, the Son of God. I have been called of him to declare his word among his people, that they might have everlasting life."
Even in the midst of one of the worst rials the Nephites ever face, persecutions, murders, marauding bands of thieves... Mormon still devotes part of his writing and record to those who are choosing to follow the Savior.
