Ephesians 6:11-14

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 and the deceits of the devil. For our struggle is not against flesh and blood [contending only with physical opponents], but against the rulers, against the powers, against the world forces of this [present] darkness, against the spiritual forces of 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]. So stand firm and hold your ground, HAVING TIGHTENED THE WIDE BAND OF TRUTH (personal integrity, moral courage) AROUND YOUR WAIST and HAVING PUT ON THE BREASTPLATE OF RIGHTEOUSNESS (an upright heart), [Is 11:5]
