Thus, we all need Christ. This appeal may prove useful any time your ministry's supporters have a specific need they don't notice. Of course, advertisers don't require a specific need in their audiences. If no need exists, they create one. During the 1960s, television commercials made dandruff a social disease comparable to leprosy.
Dandruff is simply a natural loss of scalp skin.
When advertisers made it a social horror, they were able to sell specific shampoos that supposedly healed this dread disease. They had created a need for their product. Need -demonstrate a need in your audience that is currently not being satisfied. Advertisers don't tell you that dandruff is a social evil. They show you a man and a woman meeting in a highly public place.
