11. Put on the whole armor. God has furnished us with various defensive weapons, provided we do not indolently refuse what is offered. But we are almost all chargeable with carelessness and hesitation in using the offered grace; just as if a soldier, about to meet the enemy, should take his helmet, and neglect his shield. To correct this security, or, we should rather say, this indolence, Paul borrows a comparison from the military art, and bids us put on the whole armor of God. We ought to be prepared on all sides, so as to want nothing. The Lord offers to us arms for repelling every kind of attack. It remains for us to apply them to use, and not leave them hanging on the wall. To quicken our vigilance, he reminds us that we must not only engage in open warfare, but that we have a crafty and insidious foe to encounter, who frequently lies in ambush; for such is the import of the apostle’s phrase, THE WILES (170) ( τὰς μεθοδείας) of the devil
(170) “Plutarch tells us, (Symp. l. 2., page 638,) that wrestling was the most artful and subtle of all the ancient games, and that the name of it ( πάλη) was derived from a word, which signifies to throw a man down by deceit and craft. And it is certain that persons who understand this exercise have many fetches, and turns, and changes of posture, which they make use of to supplant and trip up their adversaries. And it is with great justice, that a state of persecution is compared with it; since many are the arts, arising from the terrors of worldly evil on the one hand, and the natural love which men have to life, liberty, plenty, and the pleasures of life, on the other, that the devil makes use of to circumvent and foil them.” — Chandler.
