There is nothing like hearing a voice, listening to the pauses, and seeing the expressions on the face of the person you are trying learn from. Written words are great, but often much is lost in translation. This is why Francis Chan's DVD companion to his book, Forgotten God, is great. Frankly, I like it better than the book because Chan is just a better preacher than he is a writer. Plus, the DVD helps highlight what he thinks is most important in an expanding conversation about the Holy Spirit.
On a side note, there were a couple of themes in his book I really didn't care for, but none of them popped up in the DVD.
