As we study through Joshua and Judges we keep running into the problem of idolatry.  It is easy to dismiss this as a problem they had but we do not struggle with.  We have our idols and we keep them for a number of reasons.  One reason we keep them around is that we stay focued on what we want instead of what we need.  God is more interested in what we need than what we want.  So when He does not give in to what we want we look to other places.
