Word of the Day: "Armor of God"

This is most often used to day as a reference to Ephesians 6:10-18; 

10 Finally, my brethren, be strong in the Lord, and in the power of his might.

11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.

12 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.

In olden times, people would prepare for battle by putting on armor for personal protection. In this verse, "putting on the armor of God" doesn't literally mean putting on armor made by, or given to you from God, but rather, instead of physically putting on armor, you rely on God for protection. 

Ephesians 10 goes on to talk about the "breastplate of righteousness", the "shield of faith", and the "helmet of salvation". Again, these are not literal pieces of protection, but rather a likening of righteousness, faith, and salvation to physical armor... at least in the battle against the (unseen) spirtual enemies of Christians throughout the world.
