When we got way back into the cave Thomas gave a Family Home Evening lesson. He took all of the kid's flashlights and handed them each a map. Hhe told them it would lead them to a great treasure. Just as they had unrolled their maps, we turned off all of the flashlights. It was complete darkness. Thomas then talked about how the map was the Holy Ghost and it would lead and guide us. If we live worthy (flashlights come on) we can have the Holy Ghost with us always. If we are not making good choices (flashlights off again) we cannot tell what the Holy Ghost wants us to do.
The map led to an actual treasure. Thomas had slipped in ahead while we were all climbing down the ladder and had hidden the treasure - - bottles of Gatorade for each of us.
I think this Family Home Evening ranks up there in my top 10 of all time. Not that I have an actual list. The kids loved it too.
