Joy is a four-year-old girl who innocently misunderstood the blessing that the Lord had prepared for that day. She believes that it will rain, so she prepares for it. While looking for her rain boots, raincoat, and umbrella, she finds many silly outfits, such as a biker's jacket, a space suit, and much more.

The purpose of the book is to teach our children the Fruits of the Spirit in a fun and learning environment. Joy is one of the nine fruits. Joy is something that only comes from the Lord. Happiness comes from the abundance of joy in our hearts.
