For this phase, it's important that we learn certain presentation skills. Often we have to learn what not to do. We need to control these nervous habits. Use gestures, but use them to enhance your point, not out of nervousness. Try to avoid eating the microphone or screaming at the top of your voice during the entire sermon.
Presentation is important.
The Word of God works, if we will just get out of the way and let it work. You have to be careful how you present this precious Gospel. Remember that in a Pentecostal service, we don't conclude a message, we close it. There's a difference. If you're an insurance salesman, you want to close the deal, and get them to sign on the dotted line.
