I remember the first time I heard Dr. Ravi Zacharias speak. Having only been a Christian for a few years, I was given a cassette tape (yes, I still have a player) of a message entitled, "Absolute Truth in Relative Terms."
I had no idea who he was and I remember listening to this message and being completely in awe of the knowledge, illustrations, and compelling challenges that flowed from Dr. Zacharias's sermon.
I remember thinking, "Man, I have never heard anyone communicate in quite the same way as this guy." And I still haven't.
When Ravi speaks, it is reminiscent of an artist working on a painting. A dash of scripture here, a dab of compelling story here, and large strokes of solid truth result in a masterpiece. Many times, as with a painter, you can't quite tell what Ravi is driving at, but as he concludes his message, when the entire picture comes together, you realize what a work of art you have witnessed.
As I have said before, if you are looking for an apologetic that challenges not only the mind, but also the heart, Ravi Zacharias does it like no other.
Among his numerous publications and articles (see below), Dr. Zacharias also hosts a weekly radio broadcast appropriately titled, "Let my People Think."
Further, there is another broadcast offered through his ministry entitled "Just Thinking."
For more on Dr. Zacharias, see here.
He received his Masters of Divinity from Trinity International University in Deerfield, Illinois. Well-versed in the disciplines of comparative religions, cults, and philosophy, he held the chair of Evangelism and Contemporary Thought at Alliance Theological Seminary for three and a half years. Mr. Zacharias has been honored by the conferring of a Doctor of Divinity degree both from Houghton College, NY, and from Tyndale College and Seminary, Toronto, and a Doctor of Laws degree from Asbury College in Kentucky. He is presently Visiting Lecturer at Wycliffe Hall, Oxford University in Oxford, England.
Dr. Zacharias has been a visiting scholar at Cambridge University, where he studied moralist philosophers and literature of the Romantic era.

Ravi Zacharias is a unique, gifted communicator. I recommend his work to those who have questions about their own existence and how it relates to the God of the Bible.
Courage and Godspeed,
