Let Their Light So Shine follows the growth of the Mormon Church from a ‘fledgling New Zealand Church’ to a ‘Māori Church’ and, finally, to becoming part of the global organisation The Church of Jesus Christ of Latter-day Saints.

The recollections from direct descendants of leaders in the Church in New Zealand highlight the accomplishments and influences of these twelve men: Matene Rutatenga, James Elkington, William Roberts, Steve Watene, Pateriki Te Rei, Ian Garry, Kenneth Palmer, Nitama Paewai, Geoffrey Garlick, Ben Couch, Douglas Martin and Te Puoho Katene. Moving from the 1800s to 2010, the histories of these leaders record their experiences within the Church, their communities and their families and enable their inspiring stories to be preserved for future generations. This is the third book in the series about early leaders in the Mormon Church in New Zealand, following Turning the Hearts of the Children and By Their Fruits You Will Know Them.
