There is no 'higher' learning than what we can obtain from the Bible.

Papua New Guinea is located on an island just north of Queensland, Australia.  This particular video is focusing on the Mouk tribe ...and the name of the video is taken from their excited response of "Ee-taow!! Ee-taow!!" which means "It's true!!" (or "It's good!!  It's very good!!")

The Mouk people showed tremendous incite for a people most would say were highly uneducated.  But, the power of the truth about Jesus, not only frees us from guilt, but also from the chains and shackles of blindness which we allow ourselves to be contend with through no knowing His Light.
