Get a back pack and a lot of heavy books. Have one member of your family wear the back pack and the other members of your family hold the books. Have the person wearing the backpack run around the house or around the room and time them. Then have each family member tell about a time that someone hurt their feelings or made them mad. For each time add one of the books to the back pack. Then have the person with the back pack run again. Keep repeating until the person is too tired to run anymore. Ask them if it was easier to run with the empty backpack or the full backpack. Remind your family that when we don’t forgive, it is like adding a heavy book to the backpack. Our lives can be weighed down by bitterness and unforgiveness. Have a group prayer time where your family prays, asking God to help you forgive the people that you mentioned in the game.
