The last lesson from this study of the snow is that God has made it a symbol of purity. God is pure, and He wants us to be pure. Do you put tobacco in your mouth? Then your mouth is not pure. Do you use bad words? If so, your mouth is not pure. Do you use your eyes to read worthless story papers and books, or to look at evil pictures? Then your eyes and thoughts are not pure. Do you permit your ears to listen to improper talk? Then your ears and mind are not pure. Do you harbor bad thoughts in your heart? Then your heart is not pure. Do you defile your body by improper eating and drinking? If you do, then your body is not pure. If you and I desire to be pure, we must go to God and earnestly ask Him as David did when he cried unto God and said, "Purge me with hyssop, and I shall be clean: wash me and I shall be whiter than snow." Now let us sing this beautiful hymn: "Wash me and I shall be whiter than the snow." QUESTIONS.--About what did God ask Job, to set him thinking? Where does the snow come from? Does anyone know fully how the snow is formed? Is the snow as wonderful as it is beautiful? What do the flakes look like? Are they all formed alike? Are any two exactly alike? How is the snow useful in winter? Is snow as important in the winter as rain in the summer? Is God ever in a hurry? Are you always patient? What is worth doing well? Does God always have a purpose in whatever He does? Does God expect us to have a noble purpose? Of what is snow the symbol? Does God expect us all to be pure? PLASTIC FACE. CHARACTER IN THE COUNTENANCE. SUGGESTION:--The object used is a small plastic face such as are often sold in toy stores, and even on the streets in large cities. The head of a rubber doll would also answer the purpose. A couple of pictures of faces placed in bottles would illustrate the fact that as the faces are seen through the bottles, so our thoughts are not wholly hidden but shine through our faces. MY DEAR BOYS AND GIRLS: Here is a soft plastic face; by squeezing it on the side I can make the face very long, and it looks very sober. If I place the face between my thumb and fingers and press upon the chin and forehead it makes the face short, and makes it have a very pleasant appearance. I can make it look as though it were laughing, or make it seem to be angry and cross.
