The armor of God spiritually protects Christians from demons.
Ephesians 6:10-20: Finally, my brethren, be strong in the Lord, and in the power of his might. / Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. / For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. / Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. / Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; / And your feet shod with the preparation of the gospel of peace; / Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. / And take the helmet of salvation, and the sword of the Spirit, which is the word of God: / Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; / And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel, / For which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak.
