For each group, you’ll need: vegetable oil, dark-colored vinegar, Dawn dishwashing detergent, a tablespoon, and a small jar with a lid. Engaging Preteen Object Lesson: Unity in Christ Form groups of four. Have one child in each group pour a small amount of oil into the jar. Say: Sometimes we’re like the oil in this jar. Pour more oil in and it mixes just fine. Have a second child from each group add more oil, replace the lid, and shake the jar. Say: Add a little vinegar and look what happens. Have a third child from each group add a tablespoon of vinegar to the jar, replace the lid, and shake. The oil and vinegar don’t mix. Ask: What happened to the mixture in the jar? Say: When we meet someone different from us, we might think, “This person is just too different. How can we get along?” If we don’t accept people, we’ll never mix — or get along. Say: Let’s add a few drops of dishwashing soap and see what happens. Have a fourth child from each group add soap, replace the lid, and shake. The oil and vinegar mix. Talk to the kids in your group about what happened. What made the difference? Read Romans 15:5-7. Ask: How is Jesus like the dishwashing soap? How does Jesus make the difference in helping us accept others? Say: Let’s pray. Jesus, thank you for accepting us. Help us accept others. In Jesus, name, Amen. Looking for more preteen ideas?
