From the 2013 yearbook:
A Cult Member Finds the Truth
A Bible study was started with deaf twin brothers in a remote mountain area of the Philippines. Both belonged to a cult that believed that weapons could not harm the members as long as they wore certain amulets and scarves for protection. They had been trained in the use of knives, bolos, and guns and had participated in many battles against rebel groups in the mountains. The cult allowed them to study the Bible with the understanding that the Witnesses would not force them to leave the cult.
The brothers, of course, encouraged the twins to make their own decision based on what they were learning from the Bible. One of the twins felt that he could not make the necessary adjustments in his life in order to serve God acceptably. The other, however, kept studying. To encourage him, the brother studying with him opened the Bible and explained in sign language: “Your name, Samuel, is in the Bible. The Samuel in the Bible served the true God, Jehovah, until he was very old. You too can faithfully obey Jehovah.” This touched Samuel’s heart. “If my name is in the Bible,” he reasoned, “then I too must take Jehovah’s side.” He informed the cult that he was leaving the mountains, and he burned all his amulets and spiritistic items and made rapid progress. He is now a baptized servant of Jehovah, zealously helping other deaf ones to learn Bible truth.
