Full Armor of God

Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God. (Ephesians 6:13-17 NIV)

But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation. (1 Thessalonians 5:8 KJV)

How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth! (Isaiah 52:7 KJV)

For he put on righteousness as a breastplate, and a helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloak. (Isaiah 59:17 KJV)
