Professional prompt: How does knowing your audience affect your writing?

On my last post I emphazied the importance of understanding you audience just like Jesus Christ did. You may, or may not believe in Him, but based on the Bible, He was a pretty big guy with controvertional ideas for his time. In the Bibles we can find many instances in which Jesus Christ knew His audience, understood their needs, challenges and specific situations, and He taught them accordingly. The point is that people would stop to hear his message because they would understand it and it was given to them in a simple manner. Just like that, in modern days, understanding an audeince can make an idea stick and get to the hearts of the people.
