Rev Dr Keith Small
Originally from a ministry background, over the last 20 years Keith has been speaking to churches, university students, community lecture events, and at various training conferences in Europe and the USA concerning Muslim-Christian relations. Keith has a PhD in Islamics and New Testament Studies for his work comparing features of ancient Qur’an and New Testament manuscripts.
Keith is a Manuscript Consultant to the Bodleian Library at Oxford University, and is also an Associate Research Fellow at the London School of Theology. Keith has given various lectures concerning Islam, the Bible and the Qur’an in the OCCA over the last 6 years.
Keith’s pioneering academic book, Textual Criticism and Qur’an Manuscripts (Lexington Books, 2011), is the first book-length application to Qur’an manuscripts of textual criticism techniques used in Biblical studies and ancient Western literature. This research provides Keith with a platform for interaction at international academic Qur’anic studies conferences and with Muslim and secular Qur’an scholars from around the world. The work also has direct applications for Christian apologetics for affirming the historic textual integrity of the New Testament.
Dr Os Guinness
Os Guinness is an author and social critic. Great-great-great grandson of Arthur Guinness, the Dublin brewer, he was born in China in World War Two where his parents were medical missionaries. A witness to the climax of the Chinese revolution in 1949, he was expelled with many other foreigners in 1951 and returned to Europe where he was educated in England. He completed his undergraduate degree at the University of London and his D.Phil in the social sciences from Oriel College, Oxford.
Os has written or edited more than thirty books, including The Call, Time for Truth, Long Journey Home, Unspeakable, A Free People’s Suicide, The Global Public Square, and Renaissance. His latest book Fool’s Talk – The Recovery of Christian Persuasion was published by InterVarsity Press in June, 2015.
Before moving to the United States in 1984, Os was a freelance reporter with the BBC. Since then he has been a Guest Scholar at the Woodrow Wilson Center for International Studies, a Guest Scholar and Visiting Fellow at the Brookings Institution, and Senior Fellow at the Trinity Forum and the EastWest Institute in New York. From 1986 to 1989, Os served as Executive Director of the Williamsburg Charter Foundation, a bicentennial celebration of the First Amendment. In this position he helped to draft “The Williamsburg Charter” and later “The Global Charter of Conscience,” which was published at the European Union Parliament in 2012. Os has spoken at dozens of the world’s major universities, and spoken widely to political and business conferences on many issues, including religious freedom, across the world. He is currently a senior fellow at the Oxford Centre for Christian Apologetics in Oxford, though he still lives with his wife Jenny in the Washington DC area.
“I promise I will leave no stone unturned in my pursuit of truth.”
When former skeptic and seventeen-year-old Ravi Zacharias heard the words of Jesus in John 14:19, “Because I live, you also will live,” the trajectory of his life changed forever. In a time of helplessness and unbelief—when he was on a bed of suicide—the truth of Scripture brought hope to Zacharias, and he committed his life to Christ, promising, “I will leave no stone unturned in my pursuit of truth.” Earlier in John 14, Jesus says, “I am the way, and the truth, and the life.” This verse has become the cornerstone of Zacharias’s ultimate mission as a Christian apologist and evangelist: to present and defend the truth of Jesus Christ that others may find life in Him.
Zacharias’s calling to preach was first confirmed when he was awarded the Asian Youth Preacher Award at the international Youth Congress in Hyderabad at the age of nineteen. Years later, the Billy Graham Evangelistic Association invited Zacharias to be a plenary speaker at the inaugural International Conference for Itinerant Evangelists (“Amsterdam ‘83”) to address a gathering of 4,000 other speakers. It would be another turning point for him, as he began to seriously consider the critical need of apologetics to remove the intellectual and existential barriers that kept many skeptics from considering the truth claims of Christ. A year later, in 1984, he founded Ravi Zacharias International Ministries (RZIM).
At age 71 he remains committed to his calling to represent the gospel of Jesus Christ through historical, philosophical, and moral foundations and to defend it against objectors with grace, clarity, and coherency. He has laid the framework of the truth of the gospel to millions of people in more than 70 countries, including on the campuses of some of the world’s leading universities.
RZIM exists to reach and challenge those who shape culture with the credibility of the gospel of Jesus Christ. In 2017, Zacharias’s vision to establish an apologetics training center in the United States with global reach was realized with the launch of the Zacharias Institute in Atlanta. RZIM has sixteen offices throughout the world in the United States, Canada, Peru, Kenya, South Africa, the United Kingdom, Austria, Spain, Romania, Macedonia, Turkey, Singapore, Hong Kong, India, and the Middle East. Through its global team of speakers and more than 200 employees worldwide, RZIM seeks to impact the heart and intellect of society’s thinkers and influencers through:
- Evangelism: RZIM shares the gospel through its global team of over 80 speakers and experts as well as its radio and television programs, podcasts, and publications that reach listeners and readers around the world.
- Apologetics: A team of evangelists and trained RZIM speakers participate in open forums, speaking engagements, panels, and debates to answer objections to Christianity with gentleness and respect.
- Spiritual Disciplines: RZIM strives to model and build Christ-like character through our books, group studies, and biblical resources.
- Training: RZIM hosts a range of programs and courses in the US, UK, India, Singapore, and online, which are designed to instruct and equip all who desire to effectively contend for the Christian worldview.
- Humanitarian Support: RZIM’s humanitarian arm, Wellspring International, identifies and financially equips existing organizations aiding women and children at risk and provides individual scholarships to support education, healthcare, and basic living needs.
Zacharias has spent the past 45 years commending the Christian faith and addressing life’s great existential questions of origin, meaning, morality, and destiny with eloquence and grace. He fully believes the truth of Jesus Christ can endure the toughest critiques and philosophical attacks. He has authored or edited over 25 books in the fields of theology, apologetics, comparative religion, and philosophy. Zacharias and his wife, Margie, have been married for 45 years and have three grown children. They reside in Atlanta.
