Ephesians 6:11-13 AMP
Put on the full armor of God, [for His precepts are like the splendid armor of a heavily-armed soldier], so that you may be able to [successfully] stand up against all the schemes and the strategies of the devil. 
For our struggle is not against flesh and blood [contending only with physical opponents], but against rulers, against the powers, against the world forces of this [present] darkness, against the spiritual forces of the wickedness in the heavenly [supernatural] places.
Therefore, put on the complete armor of God, so that you will be able to [successfully] resist and stand your ground in the evil day [of danger], and having done everything [that the crisis demands], to stand firm [in your place, fully prepared, immovable, victorious].
