How can you use what you've been given?
"Suppose you can be trusted with something very little. Then you can also be trusted with something very large."
Luke 16:10a, NIrV
Ask your preteen: "How can you use what you have responsibily?" Encourage your preteen to think of things other than physical items; such as, a good work ethic, intelligence, being friendly, etc.
Responsibility is showing you can be trusted with what is expected of you.
