God's Healing Word
By: Mary Ann McNeilus, M.D

Dr Mary Ann McNeilus has been a 25+ years family friend of both Emma Magnolia and Barbara O'Neill!  She has been a long time doctor and midwife to her community.  

God’s Healing Word deals with the spiritual and mental issues one may encounter while seeking to help others. It is very comprehensive and the most beautifully written book from Mary Ann McNeilus, M.D.  It covers in depth answers for those suffering from an array of mental and emotional challenges by pointing them to the word of God.  A must read for every medical missionary!

God’s Healing Word and God’s Healing Way go together. The latter deals with the physical side offering hydrotherapy, charcoal, and other remedies while the former concentrates on the mental and spiritual maladies.

About the Author:  Dr Mary Ann McNeilus, a dedicated physician and medical missionary, was born and raised in Berrien Springs, Michigan. She pursued her education at Andrews University before obtaining an M.S. in Microbiology from the University of Michigan and an M.D. from Loma Linda University. Her medical training included a pediatric internship at the Mayo Clinic and a residency in pediatric hematology and oncology at McGill University. After marrying Marnelle McNeilus, she transitioned to Family Medicine, becoming board certified while working in Rochester, Minnesota.

In 1980, Dr Mary Ann and her husband answered a call to serve in Cambodian refugee camps through the Seventh-day Adventist World Service (SAWS), marking the beginning of their lifelong mission work. Their journey led them to medical service in Sudan and Ethiopia, where Dr Mary Ann embraced the principles of medical missionary work as outlined in the writings of Ellen White. Upon returning to the U.S., she trained at Uchee Pines Institute under Drs. Calvin and Agatha Thrash, solidifying her commitment to natural treatments and disease prevention.

Dr Mary Ann and her family established Mercy Valley Farm, a health retreat in southeastern Minnesota, where they provide holistic care, assist Amish midwives, and promote natural healing methods. She has also been instrumental in medical mission trips to Cambodia, co-authoring God’s Healing Way, a manual translated into over twenty languages to train gospel workers in health ministry.

With over twenty-five years of experience, Mary Ann has found medical missionary work to be a powerful tool for breaking down barriers and opening hearts to faith. Her passion lies in integrating physical, mental, and spiritual healing, pointing people to Jesus as the ultimate source of hope and restoration.
