Ellie Long
Missionary
Ellie Long is a young missionary from Allentown, Pennsylvania. Born in 2001, she grew up in a post-Christian culture and did not have experiences with Christians in her everyday life. She rejected theism entirely, and became very drawn to philosophy, literature, and art as a way to explain, and relate to, the dark and hopeless world around her. She unexpectedly encountered God halfway through her time at the University of Alabama, and after a period of hesitancy and questioning, believed and began working in a local church and pursuing the mission field after her graduation in 2024. She recently spent time in Southeast Asia, working with an unreached people group in a Muslim culture, and is now considering where she is going to bring the gospel to next.
