Ephesians 6:10-12

Williams(i) 10 From now on you must grow stronger through union with the Lord and through His mighty power. 11 You must put on God's full armor, so as to be able to stand up against the devil's stratagems. 12 For our contest is not with human foes alone, but with the rulers, authorities, and cosmic powers of this dark world; that is, with the spirit-forces of evil challenging us in the heavenly contest.
