"But as for us who belong to the day, let us keep our senses and have on the breastplate of faith and love and as a helmet the hope of salvation; because God assigned us, not to wrath, but to the acquiring of salvation through our Lord Jesus Christ." (1 Thess 5:8,9).
"Put on the complete suit of armour from God that you may be able to stand firm against the machinations of the devil; because we have a wrestling, not against blood and flesh, but against the governments, against the authorities, against the world rulers of this darkness, against the wicked spirit forces in the heavenly places. On this account take up the complete suit of armour from God, that you may be able to resist in the wicked day and, after you have done all things thoroughly, to stand firm.
Stand firm, therefore, with your loins girded about with truth, and having on the breastplate of righteousness, and with your feet shod with the equipment of the good news of peace. Above all things, take up the large shield of faith, with which you will be able to quench all the wicked one's burning missiles. Also, accept the helmet of salvation, and the sword of the Spirit, that is, God's Word, while with every form of prayer and supplication you carry on prayer on every occasion in spirit. And to that end keep awake with all constancy and with supplication in behalf of all the holy ones". (Eph 6:11-18).
"Out of His store He endows the upright with ability as a shield for those who live blameless lives; for He guards the course of justice and keeps watch over the way of His loyal servants." (Prov 2:7,8 NEB).
