In 2006, Tom and Cynthia Martin faced a difficult decision. They had been serving as International Mission Board missionaries in South America for 17 years, but needed to return to the United States because of medical issues. Cynthia says it was an intensely emotional time, and she grieved that she would no longer be on the front lines of cross-cultural ministry. “But God promised me that He wasn’t through with me,” says Cynthia.
