In the last 20 years, more Iranians have become Christians than in the previous 13 centuries—since Islam came to Iran. In 1979, there were an estimated 500 Christians from a Muslim background in Iran. Today, there are hundreds of thousands—some estimate more than 1 million. According to the research organization Operation World, Iran has the fastest-growing evangelical movement in the world. The second-fastest-growing church is in Afghanistan—where Afghans are being reached in large part by Iranians. The church in Iran is growing despite persecution and needs our urgent prayer.
