Offen grew up in a strict Muslim home. When a childhood friend showed him a pen that missionaries had given him for memorizing Scripture, Offen, too, wanted a pen that didn’t leak. His contact with the missionaries eventually led to his conversion. When his parents learned of his decision, his father disowned him and his mother tried to poison him. Despite many obstacles, Offen has courageously served the Malian Church for nearly 30 years. He founded Palm Tree Outreach in 2000.
