What begins as the planting of a single acorn can, by God's grace, become a mighty oak whose influence stretches far beyond what anyone could imagine. For ninety years, Bangor Worldwide Missionary Convention has inspired generations of Christians with a vision for God's global mission. Since its humble beginnings in 1936, countless lives have been shaped through faithful preaching, fervent prayer, sacrificial service, and life-changing encounters with missionaries from around the world. Rather than simply recounting the Convention's history, When God Plants Acorns tells the remarkable stories behind the movement. Drawing on newly discovered archival material, personal testimonies, and treasured memories gathered over decades, Rebecca McConnell reveals how God has worked through ordinary people to accomplish extraordinary things. From unexpected callings to lifelong friendships, from quiet acts of faithfulness to worldwide gospel impact, these pages celebrate the unseen ways God plants seeds that continue to bear fruit across generations and nations. Whether you have attended the Convention for many years or are discovering its story for the first time, this inspiring collection will encourage you to look back with gratitude, rejoice in God's faithfulness, and look forward with renewed confidence that He is still calling His people to make Christ known to the ends of the earth. Because when God plants acorns, only He knows how great the forest will become.
