Over the years, Amos has tirelessly spread the gospel through radio broadcasts and Listener Groups, bringing hope to thousands upon thousands despite the challenges of poverty and persecution. A Yao himself who converted to Christianity in his twenties, Amos has been using both traditional and new media to reach his people. He runs two FM stations which reach most of this small country, in particular areas where the Yao live. The radio programs he and his young team produce range from gospel messages to practical programs which focus on daily life, such as raising children, marriage and agriculture.

Amos spends much of his time visiting these groups, and training local group leaders and pastors. They and the group members also need a great deal of encouragement, as conversion to Christianity often leads to persecution. It is not uncommon for new believers to be beaten up and have their livestock or land confiscated by local imams and their followers. When too dangerous, new believers often move to another community where there is more protection.

One of the Listener Club leaders, Moses, was beaten up badly by several people ordered by the local imam; he bled severely in various places, and because of such danger his father advised him to leave his town. But Moses held a conviction in his heart that he should share his newfound faith with his hometown. Despite losing much of his belongings, he persisted and started a Listener Club in an enclosed yard behind his house. The Lord blessed his obedience, and today his group has about 45 people; all have become Christians.
