Fear is the natural emotional state of humanity. So many people live life in a state of constant anxiety. Think about how much fear controls what we do and say. One of the most common fears we have is of suffering injustice. We worry about having our property stolen or our bodies assaulted, and so we take precautions.
Advertisers sometimes take advantage of our fear.
Look at this advertising leaflet. I received it in my letterbox some time ago and kept it because I thought it would make a good sermon illustration. And there's a picture of a nasty looking thug with big boots kicking down your front door. Don't live in fear. What a relief.
