While there are more ways to communicate with people today, it seems good communication is harder and harder to come by.  What is the value of a person's word, does it matter anymore?  In today's text Jesus talks about the importance of truthfulness in our speech.  Why does truthfulness matter?  What affect does it have on our lives and relationships with others?  Jesus offers his followers a very simple way to approach communication.  At first glance, it seems obvious, at second glance it is a truly radical approach to life, an approach much needed today.
