Sometimes families come for counseling because children's sibling rivalry has become a problem. One way I illustrate the nature of love is to darken the room and give each parent a lighted candle. Then from oldest to youngest each child is given a candle to light from the parents' candles.
The lesson, of course, is that just as the light increases as more candles are lit, love increases as each child joins the family. Love grows. You cannot use it up. The more you love, the more love you have to give.
In my book, "How to Get Kids to Help at Home," the last chapter is about teaching values. Here are a couple of paragraphs from that book:
One Sunday school teacher taught a lesson on forgiveness. "Forgiveness," said one youngster, "is when you leave your dad's saw out in the rain, and he says it was rusty anyway." "Or," said another, "when you spill a brand new carton of milk all over the kitchen floor, and your mom says accidents will happen."
The New Testament describes love as "patient, kind, envies no one, is never boastful nor conceited, nor rude, never selfish, not quick to take offense. Love keeps no score of wrongs, does not gloat over others' mistakes." Children learn how to love from parents who love each other and then their family. Loving families bring their light to the world.
