Continuing the series through Ephesians, brother Kevin comes to the end of Chapter 1 which emphasizes that Christ is above all principality and power.
The discussion includes the Biblical indication that there are demonic forces who have geographic jurisdiction on planet earth. Christ is above them all, and will triumph over them visibly upon his return.
Meanwhile, we believers are vessels of Christ's fullness: the power of the Holy Spirit working through our lives to reach the lost, and edify the saints, so long as we remember Christ as the head.
