Tim Keller is the pastor of 5,000 member Redeemer Presbyterian Church in New York City. He is, in my judgment, the most insightful, articulate and persuasive preacher in the world today. Not only can he communicate to church people, he can also communicate to secularists and non-believers in down-to earth, compelling, reasonable, persuasive language. I have posted three videos below, all delivered in secular settings.
The talk below on The Reason for God was delivered at Google headquarters in Mountain View, California. It draws on his book of the same title. (Picture begins at the 9 second mark)
This video records Keller speaking at Google in New York City, this time invited to speak on the title of his book - The Meaning of Marriage (Picture begins at the 7 second mark)
-- "You Never Marry the Right Person" - an excerpt from Keller's book discussing one of the points in the talk
And finally, here is Tim Keller speaking in Cambridge, England on the subject of his book Counterfeit Gods.
