The child evangelism movement is when grown-ups try to teach little children about religion and about God. They use games, stories, and music to help kids learn about religion. They want kids to believe in God and to follow His teachings. Sometimes, they even give treats or prizes to kids who listen well and learn a lot about religion. Some grown-ups like this idea because they think it's important for children to learn about God and to become good religious people when they grow up.
