Any church or business that is growing is led by a good communicator. We can see from recent elections that the ability to speak clearly and persuasively is critical to one's political success. Mr. Bush is a fine man but he is a terrible communicator and McCain is not much better. Mr. Obama is untried and untested but he is a great communicator.
Sarah Palin surprised all of us with her tremendous ability to connect with people. I will be interested to see where she goes from here.
Great leaders get help so they can improve their communication. They need to communicate well in writing, interpersonal relationships and public speaking. Even Tiger Woods gets additional coaching and he is the best golfer ever. Great Pastors and Great Leaders have coaches as well.
Lloyd Ogilve was a famous Presbyterian Minister in Hollywood before taking the position as Senate Chaplain. Every sermon he gave was analyzed and discussed by a special speaking coach. The content was not discussed, that was the Preacher's job. However, the delivery, timing, pacing and tone were all fair game. That is how an expert gets better.
Who is coaching you?
Take a look at a great blog on communication. It has the top ten best and worst communicators of 2008. ( I am not on either list.)
