^Fr. Jonah, a married priest, did his all-night Akathist vigils daily from midnight to daybreak. His prayers cured the blind and cast out demons from the possessed. When Moscow doctors told an Odessa mother they could do nothing for her son who was born blind, St. Jonah prayed over his bed all night for nine days and on the morning of the tenth day, the boy could see with 20/20 vision.
