The best way to keep one’s word is not to give it. (Napoleon Bonaparte)
That statement seems to be rather cynical, doesn’t it? Of course, if you never make a promise or commitment, you’ll never fail to keep it. It used to be that a man’s word was as good as his bond. Only a handshake or a verbal agreement was enough. Today, it almost takes a lawyer to establish agreement. The Bible says our “yes” should be sufficient.
All you need to say is simply ‘Yes’ or ‘No’; anything beyond this comes from the evil one (Matthew. 5:37).
