Ephesians 6:10-15

Finally, be strong in the Lord, and in the strength of his might. Put on the whole armor of God, that ye may be able to stand against the wiles of the devil. For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world-rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places. Wherefore take up the whole armor of God, that ye may be able to withstand in the evil day, and, having done all, to stand. Stand therefore, having girded your loins with truth, and having put on the breastplate of righteousness, and having shod your feet with the preparation of the gospel of peace
