This is by far one of the warmest, most concise, well-reasoned and articulate cases I’ve seen for the existence of God lately.  Tim Keller visits Google’s Mountain View, CA, headquarters to discuss his book, “The Reason for God.” This event took place on March 5, 2008, as part of the Authors@Google series.  

His arguments are basic and well-known.  Tim Keller’s real strength seems to be his warm and humble demeanor that comes off as both sharp and friendly.  His personality is as compelling as his arguments.  I recommend you get this in the hands of your skeptic friends, use this video for a good discussion starter or the basis of an apologetics class. 

And, of course, go read his book The Reason for God: Belief in an Age of Skepticism. Its wonderful.
