Abstract: The possibility of another major world war in the near future remains quite high. Ensuring military members are spiritually resilient and ready for war is essential. The lack of spiritual resilience has led to a force that does not understand how to develop spiritually. This lack contributes to hopelessness and a higher suicide rate. The following project develops and implements a five-part curriculum to train military personnel stationed near Eglin Air Force Base on spiritual fitness through a faith-based spiritual retreat. This project is grounded in a biblical-theological framework and informed by contemporary literature on spiritual fitness and resilience and emphasizes experiential and transformative learning. The retreat includes structured sessions on Sabbath practices, solitude, devotion, and reflection, with the aim of fostering spiritual growth and resilience. The Special Operations Command Spiritual Fitness Scale (SSFS) was used for pre- and post-retreat assessments, including a 30-day follow-up, to measure the effectiveness of the retreat interventions. The findings indicate a positive shift in participants' spiritual fitness, demonstrating the retreat's potential as a model for future applications in military and civilian contexts. The project contributes to the broader discourse on spiritual resilience, offering practical resources for chaplains and religious leaders seeking to enhance spiritual fitness within their communities. Chaplains and clergy members can use the included curriculum as a guide for engaging military members needing to develop their spiritual fitness.
