I think that in the scriptures, the word they use for respect is "honor" but we don't use the word "honor" much. You can do a word study for "honor" and add a whole different dimension to this post but for now, let's use the word "respect".
What does respect mean? What does it mean to a child?
How do you grow respect in a child
for the world God made?
for him or herself?
Try reversing the order.
Actually it's more of a circle or sphere or a web of interdependence than it is a line . . .
What does it look like when the people (even children) in a group respect each other? What does it look like if they don't?
What does it look like when different age groups respect each other? When they don't?
What does it feel like when you know someone respects you? What did that person do?
What does it feel like to respect another person? How do you show them that you respect them?
How do you show respect towards other living things? Plants? Animals? What does it look like?
How do you practice respect? When you're practicing, what do you do over and over?
Can you translate this for children? Can you translate this into actions and responses that a child can do?
There's a time and a place for "No". But, for the times when kids need you to reinforce what they should be doing instead of what they shouldn't be doing. . . consider, "How do I teach respect?"
Understanding that honor and respect are the natural fiber of Biblical culture, what stories from scripture would you pick to teach kids about respect?
