In 1983, Zacharias spoke in Amsterdam at the Billy Graham Evangelistic Association's first International Conference for Itinerant Evangelists. After Amsterdam, Zacharias spent the summer evangelizing in India, where he continued to see the need for apologetic ministry, both to lead people to Christ and to train Christian leaders. In August 1984, Ravi Zacharias International Ministries was founded in Toronto, Canada, to pursue his calling as a "classical evangelist in the arena of the intellectually resistant." Today its headquarters are located in the suburbs of Atlanta, Georgia.
