Paul gives thanks to God the Father (verse 12) for delivering us from the power of darkness and moving us into the realm of light, which is the Kingdom of Christ and of God. The kingdom will come to the earth in an outward form in the thousand-year reign of Christ and then in his everlasting reign in the New Heaven and New Earth. But even now it is here in a “hidden” sense in the form of the subjects of King Jesus (his Church) being present. Satan’s kingdom also is here in this world, and it is a kingdom of darkness and sin. Only God’s power could overcome the “power of darkness” and make us children of light.
And we pray:
We give thanks to you, O Father, along with Paul for transferring us from the kingdom of darkness to the Kingdom of light. You have made us to be a light to the world, insofar as your light is in us and shines out from us. Help us to walk as children of light and to overcome the surrounding darkness of this present age.
