The purpose of this workbook is twofold. First, it is designed to increase and sustain the emotional health of future and current missionaries of the Church of Jesus Christ of Latter-day Saints. The content in this workbook can provide skills, learning, and awareness for missionaries to cultivate the necessary fortitude, emotional resilience, hope, optimism, confidence, and well-being to engage in and accomplish missionary service successfully. Second, it is aligned with the Church’s inspired updates to the seminary program, where life preparation lessons are becoming a vital component of the curriculum. This workbook not only supports mission and temple preparation but also complements the Church’s broader focus on cultivating well-rounded disciples of Jesus Christ. With an emphasis on strengthening scripture study skills and building emotional resilience, this resource is filled with practical mental health resources and teachings from latter-day prophets that provide guidance for navigating today’s increasingly complex social climate.
