Why Important: If our introduction does not arouse interest, the householder may terminate the conversation before we can give a witness. Therefore, many publishers consider their opening words to be the most important part of their presentation. Although sample presentations are provided in Our Kingdom Ministry and the Reasoning book, they do not always include a complete introduction, in order to allow for flexibility. Even if a sample presentation is complete, publishers may choose to alter it or prepare their own. Thus, we will be more effective if we carefully prepare our opening words rather than say whatever comes to mind when the householder opens the door.—Prov. 15:28.
