Prepare good-good. Study your material good-good until you understand the main ideas and see how the Bible back them. Try to make the main point them short and simple. Think about how it will help the people. Pray for holy spirit.

Use words that show that you believe your message. Don’t say the same thing in the publication word-for-word, but try to put it in your own words. The word them you use must show that you believe your message.

Show that you really convince when you talking. Talk loud enough when you giving your talk. If it will not embarrass people, you must look in their face when you talking.
