Ruth Dueck worked in Japan for 42 years with OMF International. She was involved in six church plants, working under the leadership of Japanese pastors in three of them. She came back to Canada in 2016 and works with Diaspora Returnee Ministry to reach out to Japanese students who come to Winnipeg for study.

"Ruth left her home country, Canada, in her youth to come and serve in Japan. She is even more Japanese than the Japanese. She loves the Japanese people, their country with all its natural beauty, and their culture, but above all she was a missionary who loved and served the Lord Jesus Christ with OMF International. I am confident that through this book you will see God's great deeds and His working. God sent His treasure, Ruth Dueck, to our land. And Ruth in turn brought the treasure of salvation through our Lord Jesus Christ to us. Ruth, I thank you from the bottom of my heart for serving and working in our country. Thank you." ~ Rev Kazuhiro Komido
