Dr. Hormoz Shariat was among thousands of Iranian Muslims marching in the streets of Tehran during the Islamic Revolution in 1979. Today, he’s “The Billy Graham of Iran” with a vision to reach one million Iranians for Jesus Christ. He tried Islam, but says it didn’t work to meet the needs of his heart and life.

Hormoz’s wife, Donnell, was born in America, yet she too was marching in those streets after moving to Iran — and converting to Islam — to marry Hormoz.

Today Hormoz leads Iran Alive Ministries, one of VOM’s partners in spreading the gospel to the people of Iran. Listen as Hormoz and Donnell tell the story of how God changed their hearts—and saved their marriage—through the love of Jesus and the faithful witness of His followers.

Hormoz’s new book, Iran’s Great Awakening: How God is Using a Muslim Convert to Spark Revival, releases this week.
