Encouragement!

One day, the devil was auctioning off his tools. That is, all but one tool. It was such a high price, no one could afford it. When someone asked why, he said, "That's my favorite tool. It's the tool of discouragement. I use it to pry open a life and when I get inside, I can do all kinds of damage with my other tools of hatred, lust, envy, jealousy, and pride."
