Turn off the lights in the room, and close the curtains or blinds. Ask a family member to do a simple task requiring sight, such as reading a scripture or describing a picture. Then turn on the lights, open the curtains or blinds, and ask the family member to do the task again. Discuss why it is easier to do the task with the light on. Read John 8:12, and ask family members to discuss ways that Jesus Christ is the light of the world.
