How do we know we are supporting the right cause?

Our world is full of tough choices.  Some of these are innocuous.  Some have consequences for ourselves and other people.  Here's an example.  A few weeks ago, a Christian denomination voted to ordain women into pastoral ministry.  Then, another denomination voted to affirm their stance to not involve women in leadership.  But both point to the Bible to support their claim.  These truth claims compete with one another, and we are asked to choose between them.  Which one is right?  Which one is on the side of God?  Matt and Merry explore this and other similar competing truth claims we faced throughout history and ones we face today.  How do we know we are supporting the right ones?  How do we know we are on God's side of any given issue?
