Develop children's choirs or acolyte programs that allow children of all ages to serve in worship services. What it looks like - We do not practice our faith in isolation. God set us to live among other people and to love them. Only through that sincere love do we fulfill our faith. Children will glow with pride after helping someone else.
Older children place importance in peers.
They'll be proud of being Christians when their friends are also Christians. Children will relate God's happiness to their happiness. Watch for times when kids include new children in their circle, and commend them. Accentuate our alikeness, and speak of differences as a plus in friendship instead of a minus. Recall Jesus' attitude toward people of a different race or nationality.
