Moroni thought he was finished with his record at the close of Mormon chapter 9 (see Moroni 1).  However his life was spared and he continued to write.  At both instances when he believed he was done, he included that which he felt was the most important to his readers.  Mormon 9 and Moroni 10 give great emphasis to those who receive the record to deny not the Gifts of the Spirit, or the power of God, in the many ways we might deny them.
