Through Ezekiel God lays out to Israel all He has done for them throughout their history and how they continually turned away from Him, and yet He will restore their land and they will loathe themselves one day.  The Law cannot make perfect those who draw near through sacrifices for sins time after time.  There is no longer a need for daily sacrifices as Jesus, the Great High Priest made one sacrifice for all time for those with cleansed repentant hearts.
