The Bible smuggler who bright light into the dark kingdom of Korea
Young Robert Jermain Thomas is a promising Welsh minister with a gift for new languages. For Thomas, there is no doubt God wants him to use his abilities to bring the Gospel of Jesus to the Far East. But when he suffers tragedy in China, Thomas loses direction and hope. That is, until he meets two Christian fishermen from the "Hermit Kingdom" of Korea who want to know more.
Though Christianity is illegal and Westerners forbidden, Thomas has a new mission: to bring the Word of God to the Korean people, no matter the cost. What will Thomas have to sacrifice to share God's Word with Korea?
This dvd is not in Korean, it is in English.
