The popular author and Christian teacher was known for his work through Ravi Zacharias International Ministries (RZIM), which focused on apologetic arguments for the existence of God and the reasonableness of Christianity.
He preached in more than 70 countries and authored more than 30 books in his 48-year career, teaching Christians to engage with skeptics and arguing that the Christian worldview has robust answers to humanity’s existential questions.
Zacharias was born in India and raised in an Anglican family. He recounted that his conversion to Christianity came while reading the Bible in the hospital after a failed suicide attempt as a teen. He immigrated to Canada at the age of 20.
Zacharias started his ministry with the Christian and Missionary Alliance (CMA). A graduate of Ontario Bible College (now Tyndale University) and Trinity International University, he was commissioned as a national evangelist for the United States in 1977 and ordained in the CMA in 1980. He founded RZIM in 1984, and the organization has grown to about 200 employees in 16 offices around the world, with more than 70 traveling speakers.
His best-selling book, Can Man Live Without God?, sold about 500,000 copies in 1995.
His most recent book, The Logic of God: 52 Christian Essentials for the Heart and Mind, won the Evangelical Christian Publishers Association’s 2020 Christian book award in the Bible study category.
Late in his ministry career, Zacharias faced claims that he overstated his academic background and implied he had earned a doctorate degree. Over the years, RZIM and Zacharias’s publishers revised his biographies to clarify that he has received honorary doctorates and removed references to “Dr. Zacharias.”
Zacharias was also involved in a legal dispute over “sexually explicit” communication with a woman he met through his speaking ministry. Her lawyer said Zacharias had groomed and exploited her. Zacharias sued, and the lawsuit was settled out of court with a non-disclosure agreement.
Earlier this year, doctors discovered a malignant tumor on Zacharias’s sacrum as he underwent back surgery. He began receiving treatment for sarcoma at MD Anderson Cancer Center in Houston.
The ministry posted an update on May 8 saying Zacharias’s cancer was deemed untreatable, and he was sent home to Atlanta to be with his family. On social media, a wide range of Christians including Lee Strobel, Tim Tebow, and Christine Caine posted tributes with the hashtag #ThankYouRavi.
He is survived by his wife, Margaret, and their three children.
