Colossians 1:21-23 (Reconciliation in the Bible)

What does reconciliation mean in the Bible?  The apostle Paul in Colossians 1:21-23 helps bring clarity to the before and after picture of salvation and how we move from being enemies of God to part of His family.  We are changed into those who are holy, without blemish, and free of accusation. This is reconciliation with God.
