This is for those of us who don’t have snow where we live.
This illustration is awesome if you have an area of sand (playground, beach) around you meeting place. I gathered them together and wrote out the word “sin” in the sand with red food colored water. Then, I asked them to shout out sins that people commit against God. As they shouted out the sins, I marked the sand with a streak of red until the bottle was emptied and we were left with a red stained area in front of us. I then read from Isaiah 1:18-20 and told them about the saving Grace of God. To finish, I had them kick the sand over the red stained area to make it white again. Every kick represented a sin or temptation in their own lives that Jesus has forgiven.
