The Four Steps of Lesson Preparation:

 1. Information - To study your lesson you read the Scriptures, the comments the lesson writers have to make about the Scriptures, and perhaps you refer to other sources to complete your understanding of the lesson subject.

2. Incubation - A period of brooding or reflecting or meditating upon the information you have obtained. You think it over, having in mind your class, each pupil in your class, and the needs of each pupil. You consider the methods for conveying the information to your pupils in the most effective way. You talk to God about the lesson, and about your pupils, and ask for His help.

3. Illumination - You catch the point, you see clearly what is to be done and how it is to be done. You become enthusiastic over the possibilities and are eager to "get the lesson into shape" for presentation.

4. Verification or Revision - This is "getting the lesson into shape," making an outline.
