Colossians 2:10:
And ye are complete in him [Christ], which is the head of all principality and power:
Notes on Colossians 2:10:
This is yet another Scripture proving that God has already done everything for you to provide what you need in this life. This goes right along with the facts that God has already given to you all things pertaining to life and godliness (2 Peter 1:3) and that He has already blessed you with all spiritual blessings (Ephesians 1:3). You do not have to try to weasel blessings out of God. As far as He is concerned, they are already granted. All you need to do is receive the blessings that God already offers you, including healing.
Because Jesus is the Head over ALL principality and power, you know that He has dominion over the devil and all his cohorts who operate on the earth. Because you are in Christ, you are partaker of His dominion.
