The book of 3 John is a letter written to a church about 85 to 95 AD. It is only 15 verses long, but in those 15 verses the word “truth” or ‘true” is used 7 times. When a word is used that many times in such a short space it emphasizes the importance of that word to the writer and to the ones written to. Obviously, John thought truth was something this church needed to be reminded of. Why? Part of the reason is because there was a man in this church who had a problem with truth. He opposed the authority and teaching of John himself by slandering him. Also, he wouldn’t allow Christian missionaries that came to the church to preach the truth. This man’s name was Diotrephes and he was guilty of a very serious sin, but a very common sin, a sin that’s alive and well in the world today and even in some churches. What is this sin? It’s the First Sin. Listen along and discover just what this sin is.
