I have heard that the musical "The Book of Mormon," which has performances this week in Nashville, is witty and well-written. It follows the fictional adventures of two missionaries from The Church of Jesus Christ of Latter-day Saints serving in Uganda. I have also heard that one of the themes of the musical is that people of faith are naive if they believe their faith can help make the world a better place.
As a former full-time missionary for The Church of Jesus Christ of Latter-day Saints, I understand the value of faith in changing individual lives and communities.
