An Advent of Peace

Over the centuries from the beginning of time, the Lord has sent promise after promise, prophecy after prophecy, of the Seed of the Woman who would deliver us from Satan, Death, Sin and Our Own Heart.  In the fullness of time, a baby is born in Bethlehem, and the angels cannot contain themselves!  "Glory to God in the highest!  And on earth, peace to men on whom His favor rests!" (Luke 2:14)  The promise of peace is finally here!  But what is this peace?  It has so many interpretations and iterations in our modern society.  Are they all correct?  Or does God have something more specific in mind?  From Luke 2:1-14.
