The life of Isaac Liu, son of Brother Yun, the Heavenly Man

Isaac Liu, the son of Brother Yun, tells his own story of growing up under the hostile eyes of the Chinese authorities In the months before Isaac’s birth, Brother Yun was in prison. His mother was about to be forced into having an abortion, though seven months pregnant, because she was carrying the child of an enemy of the state. After desperate prayer, the night before she was due to go into a hospital for the operation, she miraculously gave birth.Isaac met his father for the first time at the age of four. With Brother Yun constantly on the run, and his mother working to feed the family, Isaac’s grandmother cared for him. One day his mother was also arrested. Isaac and his sister were swiftly taken by local Christians to another town, where they registered at a school under false names. The family finally managed to flee to Burma, then to Thailand, and ultimately to Germany.Isaac’s mother had prayed that God would not call her son to be an evangelis–but his father had dedicated him to God. Isaac, now in his twenties, has embraced the call to be a pastor.
