Lesson from Gwammie tells the story of a grandmother explaining faith and church to her three grandchildren: Bumble Bee, Doodle Bug, and Chipmunk. After arriving to spend the day with Gwammie, the three children ask a series of questions to understand why Gwammie is so happy. Gwammie explains why going to church and spending time with God brings her peace and happiness. This leads to a series of questions about God, Jesus, the Holy Spirit, church, religion, faith, and how to live and be yourself. All this is a bit much for the children to understand, so Gwammie comforts them and explains they don't need to rush because they have their whole lives to learn.

The story is inspired by real conversations the author has had with her grandchildren. It is meant to inspire parents and grandparents to share their faith with their children and grandchildren in a world that seems to be turning away from God and religion. Just by living our faith and sharing our joy, we can inspire the next generation to embrace what is offered through God's greatest gift, Jesus Christ. Although Catholic-inspired, this story can be shared by anyone who believes in our Lord and Savior and who wants to start a simple conversation with children about faith and church.
