It is estimated that 20 million Chinese lost their lives during Mao’s Cultural Revolution. Christians stood firm in what was probably the most widespread and harsh persecution the Church has ever experienced. The persecution purified and indigenized the Church. Since 1977 the growth of the Church in China has no parallels in history. Researchers estimate that there were 30–75 million Christians by 1990. Mao Zedong unwittingly became the greatest evangelist in history.
