14. Stand therefore. Now follows a description of the arms which they were enjoined to wear. We must not, however, inquire very minutely into the meaning of each word; for an allusion to military customs is all that was intended. Nothing can be more idle than the extraordinary pains which some have taken to discover the reason why righteousness is made a breastplate, instead of a girdle. Paul’s design was to touch briefly on the most important points required in a Christian, and to adapt them to the comparison which he had already used.

Truth, which means sincerity of mind, is compared to a girdle. Now, a girdle was, in ancient times, one of the most important parts of military armor. Our attention is thus directed to the fountain of sincerity; for the purity of the gospel ought to remove from our minds all guile, and from our hearts all hypocrisy. Secondly, he recommends righteousness, and desires that it should be a breastplate for protecting the breast. Some imagine that this refers to a freely bestowed righteousness, or the imputation of righteousness, by which pardon of sin is obtained. But such matters ought not, I think, to have been mentioned on the present occasion; for the subject now under discussion is a blameless life. He enjoins us to be adorned, first, with integrity, and next with a devout and holy life.

15. And your feet shod. The allusion, if I mistake not, is to the military greaves; for they were always reckoned a part of the armor, and were even used for domestic purposes. As soldiers covered their legs and feet to protect them against cold and other injuries, so we must be shod with the gospel, if we would pass unhurt through the world. It is the gospel of peace, and it is so called, as every reader must perceive, from its effects; for it is the message of our reconciliation to God, and nothing else gives peace to the conscience. But what is the meaning of the word preparation? Some explain it as an injunction to be prepared for the gospel; but it is the effect of the gospel which I consider to be likewise expressed by this term. We are enjoined to lay aside every hinderance, and to be prepared both for journey and for war. By nature we dislike exertion, and want agility. A rough road and many other obstacles retard our progress, and we are discouraged by the smallest annoyance. On these accounts, Paul holds out the gospel as the fittest means for undertaking and performing the expedition. Erasmus proposes a circumlocution, (ut sitis parati,) that ye may be prepared; but this does not appear to convey the true meaning.

16. Taking the shield of faith. Though faith and the word of God are one, yet Paul assigns to them two distinct offices. I call them one, because the word is the object of faith, and cannot be applied to our use but by faith; as faith again is nothing, and can do nothing, without the word. But Paul, neglecting so subtle a distinction, allowed himself to expatiate at large on the military armor. In the first Epistle to the Thessalonians he gives both to faith and to love the name of a breastplate, — “putting on the breastplate of faith and love,” (1 Thessalonians 5:8.) All that was intended, therefore, was obviously this, — “He who possesses the excellencies of character which are here described is protected on every hand.”

And yet it is not without reason that the most necessary instruments of warfare — a sword and a shield — are compared to faith, and to the word of God. In the spiritual combat, these two hold the highest rank. By faith we repel all the attacks of the devil, and by the word of God the enemy himself is slain. If the word of God shall have its efficacy upon us through faith, we shall be more than sufficiently armed both for opposing the enemy and for putting him to flight. And what shall we say of those who take from a Christian people the word of God? Do they not rob them of the necessary armor, and leave them to perish without a struggle? There is no man of any rank who is not bound to be a soldier of Christ. But if we enter the field unarmed, if we want our sword, how shall we sustain that character?

Wherewith ye shall be able to quench all the darts. But quench appears not to be the proper word. Why did he not use, instead of it, ward off or shake off, or some such word? Quench is far more expressive; for it is adapted to the epithet applied to darts The darts of Satan are not only sharp and penetrating, but — what makes them more destructive — they are fiery Faith will be found capable, not only of blunting their edge, but of quenching their heat.

“This,” says John, “is the victory that overcometh the world, even our faith.” (1 John 5:4.)

17. And take the helmet of salvation. In a passage already quoted, (1 Thessalonians 5:8,) “the hope of salvation” is said to be a helmet, which I consider to be in the same sense as this passage. The head is protected by the best helmet, when, elevated by hope, we look up towards heaven to that salvation which is promised. It is only therefore by becoming the object of hope that salvation is a helmet.

18. Praying always with all prayer. Having instructed the Ephesians to put on their armor, he now enjoins them to fight by prayer. This is the true method. To call upon God is the chief exercise of faith and hope; and it is in this way that we obtain from God every blessing. Prayer and supplication are not greatly different from each other, except that supplication is only one branch of prayer

With all perseverance. We are exhorted to persevere in prayer. Every tendency to weariness must be counteracted by a cheerful performance of the duty. With unabated ardor we must continue our prayers, though we do not immediately obtain what we desire. If, instead of with all perseverance, some would render it, with all Earnestness, I would have no objection to the change.

But what is the meaning of always? Having already spoken of continued application, does he twice repeat the same thing? I think not. When everything flows on prosperously, — when we are easy and cheerful, we seldom feel any strong excitement to prayer, — or rather, we never flee to God, but when we are driven by some kind of distress. Paul therefore desires us to allow no opportunity to pass, — on no occasion to neglect prayer; so that praying always is the same thing with praying both in prosperity and in adversity.

For all saints. There is not a moment of our life at which the duty of prayer may not be urged by our own wants. But unremitting prayer may likewise be enforced by the consideration, that the necessities of our brethren ought to move our sympathy. And when is it that some members of the church are not suffering distress, and needing our assistance? If, at any time, we are colder or more indifferent about prayer than we ought to be, because we do not feel the pressure of immediate necessity, — let us instantly reflect how many of our brethren are worn out by varied and heavy afflictions, — are weighed down by sore perplexity, or are reduced to the lowest distress. If reflections like these do not rouse us from our lethargy, we must have hearts of stone. But are we to pray for believers only? Though the apostle states the claims of the godly, he does not exclude others. And yet in prayer, as in all other kind offices, our first care unquestionably is due to the saints.

19. And for me. For himself, in a particular manner, he enjoins the Ephesians to pray. Hence we infer that there is no man so richly endowed with gifts as not to need this kind of assistance from his brethren, so long as he remains in this world. Who will ever be better entitled to plead exemption from this necessity than Paul? Yet he entreats the prayers of his brethren, and not hypocritically, but from an earnest desire of their aid. And what does he wish that they should ask for him? That utterance may be given to me. What then? Was he habitually dumb, or did fear restrain him from making an open profession of the gospel? By no means; but there was reason to fear lest his splendid commencement should not be sustained by his future progress. Besides, his zeal for proclaiming the gospel was so ardent that he was never satisfied with his exertions. And indeed, if we consider the weight and importance of the subject, we shall all acknowledge that we are very far from being able to handle it in a proper manner. Accordingly he adds,

20. As I ought to speak; meaning, that to proclaim the truth of the gospel as it ought to be proclaimed, is a high and rare attainment. Every word here deserves to be carefully weighed. Twice he uses the expression boldly, — “that I may open my mouth boldly,” “that therein I may speak boldly.” Fear hinders us from preaching Christ openly and fearlessly, while the absence of all restraint and disguise in confessing Christ is demanded from his ministers. Paul does not ask for himself the powers of an acute debater, or, I should rather say, of a dexterous sophist, that he might shield himself from his enemies by false pretences. It is, that I may open my mouth, to make a clear and strong confession; for when the mouth is half shut, the sounds which it utters are doubtful and confused. To open the mouth, therefore, is to speak with perfect freedom, without the smallest dread.

But does not Paul discover unbelief, when he entertains doubts as to his own stedfastness, and implores the intercession of others? No. He does not, like unbelievers, seek a remedy which is contrary to the will of God, or inconsistent with his word. The only aids on which he relies are those which he knows to be sanctioned by the Divine promise and approbation. It is the command of God, that believers shall pray for one another. How consoling then must it be to each of them to learn that the care of his salvation is enjoined on all the rest, and to be informed by God himself that the prayers of others on his behalf are not poured out in vain! Would it be lawful to refuse what the Lord himself has offered? Each believer, no doubt, ought to have been satisfied with the Divine assurance, that as often as he prayed he would be heard. But if, in addition to all the other manifestations of his kindness, God were pleased to declare that he will listen to the prayers of others in our behalf, would it be proper that this bounty should be slighted, or rather, ought we not to embrace it with open arms?

Let us therefore remember that Paul, when he resorted to the intercessions of his brethren, was influenced by no distrust or hesitation. His eagerness to obtain them arose from his resolution that no privilege which the Lord had given him should be overlooked. How absurdly then do Papists conclude from Paul’s example, that we ought to pray to the dead! Paul was writing to the Ephesians, to whom he had it in his power to communicate his sentintents. But what intercourse have we with the dead? As well might they argue that we ought to invite angels to our feasts and entertainments, because among men friendship is promoted by such kind offices.
