By "Challenging Religion" I mean the Religion that people have come to love and embrace that is Tradition and Doctrin. It would be defined under #4 from Merriam-Webster. And religious as defined in # 2.  Being devoted to the belief or observances and not to God himself.  

Oh yes, we love our religion.  We embrace it and how dare anyone try to change our minds or give us insight.  The possibility that there might me more to learn and know about God is ridiculous, right?  The Bible's definition of religion that is pure and undefiled before God is found in James 1:27

- Pure Religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world. 

-- Just that.  No rituals, ceremonies, mantras, doctrins or traditions.  Don't get me wrong not all doctrin and traditions are bad.  But when our devotion is to the tradition or doctrin and not to God, then it is defiled.  Let's seek the Kingdom of God and His righteousness instead of striving to be perfect in our doctrins and rituals.  Let's love God so much that we desire to know everything about him we can know.  So much that we live an unspotted life from the world.  Let our works be only fruits and not roots.
