Propel is Christian Challenge AZ's annual leadership training retreat. New and experienced student leaders from campuses across the state gather for a weekend of connecting, training, prayer, and worship. Propel helps campus missionaries cast the vision, mission, and values of Christian Challenge to new student leaders and helps prepare for effective outreach to freshmen in the fall. Training includes instruction for Gospel appointments, Challenge Communities, and missions opportunities. Students also engage in prayer times and meet with their local campus missionaries to discuss specific tactics to reach their college campus.
