Ephesians 6:13

13. Wherefore In view of the supernatural powers you have to encounter. Surely a divine armour, and the whole we can use, are necessary for a supernatural battle. Of the whole armour St. Paul mentions six pieces; four fixed in contact upon the body, namely: the girdle or belt, breastplate, sandals, and helmet; and two in the hands, the shield and the sword. All are protective but the last. And he mentions them in the order in which the warrior would be apt to put them on for battle. First, as preliminary to all easy action, he binds his loose tunic in the girdle, then puts the breastplate or coat of mail upon his chest. Then taking his shield in his left hand, with his right hand he first puts on his helmet, and then, taking his sword, is ready for the battle. Paul’s soldier is thoroughly protected, save that the legs do not seem to have their greaves or buskins.

In the evil day Wherever or whenever the evil day comes, and whether it consist of adversity, temptation, or onslaughts of infidel advocates. Having done all of duty, whether of arming or fighting. To stand firmly and perpendicularly; in contrast with falling, running, or being captured. But, in fact, in this battle the only failure is cowardice or apostasy; he who truly fights is never conquered. He is sure, after the rush of battle has past, to stand. Just so in our national ballad, after the night of cannonade is over, and the morning dawns ”that flag is still there.”
