I also love this story and used it many times in lessons at church!

In my local church congregation, one of our leaders asked us to go home as a family and come up with a motto. This was an excellent exercise to help define what is truly important to you as a family, or a standard by which you all want to live. The one my family came up with (our last name begins with a C, thus all of the C words) an addition problem.

Commandments

Charity

= Countenance of Christ

We shall look like Him, because we have learned to be like HIM.
