In this video Tim Keller is explaining the main ideas of his book, "The Reason for God" at the Google campus in Mountain View, California. Tim is someone who can calmly and knowledgeably share the Gospel with even the smartest most skeptical people.

I was inspired to share this with you because of a conversation I had with two very intelligent non-Christian men about God. They ask me about my Bible when I was sitting in a Starbucks, and it set off an hour long conversation about why Jesus is the world's only hope. Thankfully from listening and reading the teaching of wise Christian men, like Keller and Francis Schaeffer, I was able to answer most of their questions about God. Listen to this talk and read his book—it will be worth it.
