Display verse in classroom. Choose a student to begin the “chain of harmony” by saying “(name), live in harmony with one another, be sympathetic, love as brothers, be compassionate and humble,” then link elbows. The student then selects another student, repeats the verse using that student’s name, and they then link arms. Continue the activity until every student is linked together in a chain of harmony. Close with a simple prayer that asks Jesus to help the class treat everyone the way Jesus treated people.
