At yesterday’s feast of Christ the King, we read the Colossians hymn in which St. Paul spoke of Christ’s power to deliver us:
Let us give thanks to the Father, who has made you fit to share in the inheritance of the holy ones in light. He delivered us from the power of darkness and transferred us to the kingdom of his beloved Son, in whom we have redemption, the forgiveness of sins (Col 1:12–14).
So, what is deliverance? It is what happened to you when Christ took you out of the kingdom of darkness and transferred you to the Kingdom of Light, to the Kingdom of His beloved Son.
