Watching a little daytime TV today, which I simply don't do, I was amazed at some of the ads. They're very much like those little ads in the back of magazines come to life.
Zit medicine and novelty trinkets, including a cross necklace that has a tiny tiny version of the Lord's Prayer inside. Hold it up to your eye and you'll be stunned!
The phrase "spiritual accessory" was actually used to describe it. You too can have the Lord's Prayer close to your heart, as an external thing, dangling there, and always handy in case you forget what it says. You can lift it to your eye and read the little print.
