Have the children gather around a table to see the two magnets.
If you have a larger class, use an overhead projector to shine the
shadows of the magnets on the wall for everyone to see. Ask
the children what makes a person a friend. (Allow the
children to respond.) The Proverbs 18:24b says that
"there is a friend that sticks closer that a brother."
To illustrate this, place a magnet on the table, and then bring
the other magnet close to it so that it draws the first magnet to
it. The magnets are acting like friends. When people
are friends, they like to be close to each other. Next, show
the children what happens when someone is not friendly by putting
a magnet on the table, then bring the other magnet close with the
opposite pole facing the first magnet so it repels the magnet.
The magnets are not acting like friends now. Sometimes the
children will not want to play together or get angry with each
other. Sometimes they will act like the magnets are acting
17:17 says, "A friend loves at all times." Though
other children may sometimes do or say things that a child does
not like, that child must remember to love at all times. God
has given them those friends. Have the magnets draw close to
each other again to show that being friends means that each child
must learn to love at all times.
