Gospel of John, Chapter 6, verses 44-51
Jesus continues talking to the crowds (read: us) on two levels.  The first is how we yearn and long for something beyond us - and that emptiness and longing can never be filled by anything other than God.  But the second - and He is becoming more and more explicit about this - is that His Flesh is what fills that yearning.  So how do we make sense of this?  Or not?
