Ephesians 6:10-12

Now my beloved ones, I have saved these most important truths for last: Be supernaturally infused with strength through your life-union with the Lord Jesus. Stand victorious with the force of his explosive power flowing in and through you. Put on God’s complete set of armor provided for us, so that you will be protected as you fight against the evil strategies of the accuser! Your hand-to-hand combat is not with human beings, but with the highest principalities and authorities operating in rebellion under the heavenly realms. For they are a powerful class of demon-gods and evil spirits that hold this dark world in bondage.
