Most churches have older adults who can no longer teach, but are dependable prayer warriors. Enlist a prayer partner for each children's class. Give them a printout listing names of all pupils. The prayer partners pledge to pray daily for the names on their list.
If possible, prayer partners should occasionally visit the class for which they are praying, so pupils can become acquainted with them. Boys and girls will be encouraged to know someone cares enough to pray daily for them.
