Avoid drawing attention to yourself. As God's humble servants, we should seek to honor him in all that we do and say. Emphasize the Scriptures rather than your own ideas. Jokes and humorous stories are not necessary and often detract from the power of the Scriptures. The Bible does not indicate that Jesus used such devices.
Logical development is a key ingredient in effective teaching.
It makes a presentation persuasive and easy to follow. Present specific material as Jesus did. When giving instructions, explain how they are to be executed. Do not introduce more material than can be adequately developed in the allotted time. Keep your presentation simple, uncomplicated.
