Welcome to Moody Presents with Mark Jobe … president of Moody Bible Institute.  With all that is going on in our culture, some people may raise an eyebrow when they hear that this series is called Defiance ... but we're not saying that we should take to streets … and start protesting or rioting.  We are talking about taking a spiritual stand and today, a tough not often talked about topic.  It is the call to purity.
