"On August 6, just two days before the Olympics began, Pastor Zhang "Bike" Mingxuan was arrested, along with his wife and a coworker. In response to these arrests, The Voice of the Martyrs and China Aid Association have launched a petition drive to free these three Christians and to let the Chinese government know that the world is aware that these Christians are being detained.
Pastor Bike, as he is affectionately known, is considered to be one of the most outspoken evangelists in China. He is a bold believer willing to cross borders, hand out Christian literature and Bibles, share Christ with those under age 18 and lead thousands to Christ. All these actions are considered "illegal," in communist China. Earlier this year, Pastor Bike pleaded with VOM staff and China Aid Association to create the China Prayer Bands so that Christians in the free world could know more about persecution of Christians in China."
