Just as light carries the photograph or picture, so the air carries the sound of our words and other vibrations of the atmosphere which we call sound. Thus you see the light is one book and the air is another, and God doubtless has many other forms of making and keeping the record of our actions and words--yes, even of our thoughts, and in the great Judgment Day these words which we utter will say themselves over again in our ears. If you uttered any bad or wicked words yesterday or to-day, or shall do so tomorrow, remember you will have to give an account of them in the great Day of Judgment. But there is another thing connected with our uttering of bad words, as well as the fact that we must give an account of them. Bad words are connected with bad thoughts, and so every bad word which we utter indicates the character of our thoughts and has a bad influence upon our minds and hearts. Not only do these words record themselves upon the atmosphere, but they also record themselves in a lasting--yes, in an eternal influence upon the hearts and the minds and the lives of those who hear them. Just the same as the words which are spoken into a phonograph are recorded and can be repeated over and over many times, so the bad words and the wicked thoughts which are expressed into the ears of others make an indelible record upon their thoughts and hearts, and are oftentimes repeated to others, thus multiplying the record, and at last all these records will appear against us in the great Day of Judgment. How careful you and I should be to speak only good words and to think only good thoughts. QUESTIONS.--Has God other record books beside the one of deeds? What does one of the other books record? What is a telephone? What is a phonograph? What happens to the air when our words strike it? What are these air-vibrations called? What does the air do with sound? What two things may be used as God's recording books? Must all bad words be accounted for? What do bad words indicate? Upon what instrument can words also be recorded? Are all words like those which are recorded by a phonograph? Why? (Permanent). Will God hold these records against us on the Judgment Day? MAGNET AND NEEDLE. GOD'S GUIDING HAND. SUGGESTION:--Objects used: A magnet, a piece of paper and an ordinary sewing needle. In the illustration lay the needle flat against the paper directly under the magnet. The ordinary magnet, purchased for a few cents in a toy store, will answer the purpose.
