In this series of sermons, Jeff Niell, pastor of Emmanuel Covenant Church in Phoenix, Arizona, teaches on the Apostle James's warnings and instruction with regard to the tongue. Are Christians guilty of using their tongues to harm their brothers instead of using them as instruments of righteousness? How do we encourage one another with the tongue? What are the obvious, and not so obvious, improper uses of the tongue? How do we glorify God in our speech? What about oaths; can Christians take them or swear by anything? Pastor Niell addresses these questions and many others in this series.
