What are the primary elements of a video illustration?  There has to be an opening image, an attention-getter. And there has to be an ending image, something you want to leave the congregation with. In between there can be anything you like to get the Word across. You can use the same content as a parable, or fall back on standard elements:

• Setting – evoking a mood by presenting a background that people will recognize, e.g. the Holy Land

• Theme – presenting the main idea, e.g. Love of Neighbor

• Point of View – demonstrating a point of view, e.g. Stewardship

• Character – developing a character through their action, e.g. Acting on the basis of Love

Whatever the content, remember that the objective is to get the congregation thinking along the same lines as the preacher. If you can do that, then you’ve succeeded.
