Once upon a time it was announced that the devil was going out of business and would sell all his equipment to those who were willing to pay the price.
On the big day of the sale, all his tools were attractively displayed. There was Envy, Jealousy, Hatred, Malice, Deceit, Sensuality, Pride, Idolatry, and other implements of evil on display. Each of the tools was marked with its own price tag.
Over in the corner by itself was a harmless-looking, wedge-shaped tool very much worn down, but still it bore a higher price than any of the others. Someone asked the devil what it was, and he answered, "That is Discouragement." The next question came quickly: "And why is it priced so high even though it is plain to see that it is more worn than these others?"
"Because," replied the devil, "it is more useful to me than all these others. I can pry open and get into a person's heart with that when I cannot get near him with any other tool. Once I get inside, I can use him or her in whatever way suits me best. It is worn well because I use it on everybody I can, and few people even know it belongs to me."
This tool was priced so high that no one could buy it, and to this day it has never been sold. It still belongs to the devil, and he still uses it on people of all kinds.
