Knowing what you believe ..why..and how to communicate it effectively

I watched Voddie Baucham on 722 tonight give an awesome sermon on what to say to those who believe that what the Davinci Code portrays is truth The picture is from 722 and is the bottom line as to why you can believe what you believe and communicate that effectively about the Bible I think the key to all of this is communicating what you believe in a loving way...not argument
