Mary Elizabeth Garrison (1926–2013) was born and raised in the hills of Alabama. She wrote and published five books on Christian life, including How to Try a Spirit; How to Conduct Spiritual Warfare; The Keys to the Kingdom Are Binding, Loosing, and Knowledge; The Holy Ghost and Mrs. Garrison; and How to Keep the Ten Commandments. Mary started a ministry called Christ Camp Ministries in Florida and Alabama. While doing missionary work, she felt that she was not only called to preach the Gospel, but also to heal the sick and cast out demons.
