Our text today deals with the terrible danger of being spiritually deceived. We live in an age that is well supplied with impersonators, pitch men and con artists. I once heard of a farmer whose horses kept slobbering over everything. He saw an advertisement in a farm magazine offering a cure for this for a fee of $20. He scraped together the money and wrote asking for the secret. In return he received a very thin envelope containing a single sheet of paper, on which were written the words, "Teach your horses to spit."
