Ruth Presswood Hutchins In 1970, to fulfill the request of Rev. J.C. Pollock, an author from England, Ruth Presswood Hutchins wrote at considerable length about the life and ministry of Ernest Presswood. At that time, a conviction came upon her that she had a story to be told, a story that had taken her 20 years to forget. She began to pray about the matter. The task seemed too great. It took her 20 years to remember, research, organize and write No Sacrifice Too Great. It is the story of her life, especially the years in the Netherlands East Indies as the wife of the pioneer missionary, William Ernest Presswood. Those years included internment by the Japanese during World War II and the tragedy of its aftermath.
