For about 80 cents a child, The Mailbox Club walks a kid through a complete course of Bible lessons. Last year: 17.3 million children enrolled, nearly 12 million completed the course, and 8 million made a decision for Christ — across 100+ countries, 200,000 churches, and 750,000 volunteer mentors.

In this Partner Highlight, Tim talks with John Mark Eager, CEO of The Mailbox Club, about how a 1965 mail-based Bible lesson ministry in Valdosta, Georgia became a globally decentralized, church-driven discipleship engine serving the 4–14 age group in the hardest-to-reach places on earth. They cover the Samaritan's Purse distribution pivot that dropped costs and 10×'d graduation rates, the 10/40 Window math, why discipleship-first flips the math (80%+ of kids discipled come to faith anyway), and Franklin Graham's counsel when John Mark laid out a growth plan: "Don't limit God."
