A voice says "Yawp" And I said "What shall I yawp?" Isaiah 40v6 (JGV)

I spent some time yesterday talking to a young preacher. We discussed various aspects of the art. One of the elements that I think makes for great preaching is when the preacher finds his own voice. That is key. I used the above to illustrate my point.
It's a great clip and in many ways it illustrates how the preacher begins to find his own voice and also the preacher's task of unlocking what God has put in other people.
