The "helmet of salvation" is worn by the Lord Himself, as He is depicted by the prophet coming to the succour of His people (Isai. lix. 17). This helmet, on the head of Jehovah, is the crest and badge of their Divine champion. Given to the human warrior, it becomes the sign of his protection by God. The apostle does not call it "the _hope_ of salvation," as he does in 1 Thessalonians v. 8, thinking of the believer's assurance of victory in the last struggle. Nor is it the sense and assurance of past salvation that here guards the Christian soldier. The presence of his Saviour and God in itself constitutes his highest safeguard.
"O Jehovah my Lord, the strength of my salvation, Thou hast covered my head in the day of battle."
The warrior's head rising above his shield was frequently open to attack. The arrow might shoot over the shield's edge, and inflict a mortal blow. Our faith, at the best, has its deficiencies and its limits; but God's salvation reaches beyond our highest confidence in Him. His overshadowing presence is the crown of our salvation, His love its shining crest.
Thus the equipment of Christ's soldier is complete; and he is arrayed in the full armour of light. His loins girt with truth, his breast clad with righteousness, his feet shod with zeal, his head crowned with safety, while faith's all-encompassing shield is cast about him, he steps forth to do battle with the powers of darkness, "strong in the Lord, and in the might of His strength."
6. It only remains that "the _sword_ of the Spirit" be put into his right hand, while his lips are open in continual prayer to the God of his strength.
The "cleansing word" of chapter v. 26, by whose virtue we passed through the gate of baptism into the flock of Christ, now becomes the guarding and smiting word, to be used in conflict with our spiritual foes. Of the Messiah it was said, in language quoted by the apostle against Antichrist (2 Thess. ii. 8): "He shall smite the earth with the rod of His mouth, and with the breath of His lips shall He slay the wicked" (Isai. xi. 4). Similarly, in Hosea the Lord tells how He has "hewed" the unfaithful "by His prophets, and slain them by the words of His mouth" (Hos. vi. 5). From such sayings of the Old Testament the idea of the sword of the Divine word is derived. We find it again in Hebrews iv. 12: "The word of God, living and active, sharper than any two-edged sword"; and in the "sword, two-edged, sharp," which John in the Revelation saw "coming out of the mouth of the Son of man": it belongs to Him whose name is "the word of God," and with it "He shall smite the nations."[174]
This sword of the inspired word Paul himself wielded with supernatural effect, as when he rebuked Elymas the sorcerer, or when he defended his gospel against the Judaizers of Galatia and Corinth. In his hand it was even as
"The sword Of Michael, from the armoury of God, ... tempered so that neither keen Nor solid might resist that edge."
With what piercing reproofs, what keen thrusts of argument, what double-edged irony and dexterous sword-play did this mighty combatant smite the enemies of the cross of Christ! In times of conflict never may such leaders be wanting to the Church, men using weapons of warfare not carnal, but mighty to "cast down strongholds," to "bring down every high thing that exalts itself against the knowledge of God and make captive every thought to Christ's obedience."
In her struggle with the world's gigantic lusts and tyrannies, the Israel of God must be armed with this lofty and lightning-like power, with the flaming sword of the Spirit. No less in the secret, internal conflicts of the religious life, the sword of the word is the decisive weapon. The Son of man put it to proof in His combat in the wilderness. Satan himself sought to wrest this instrument to his purpose. With pious texts in his mouth he addressed our Lord, like an angel of light, fain to deceive Him by the very Scripture He had Himself inspired! until, with the last thrust of quotation, Jesus unmasked the tempter and drove him from the field, saying, "Get thee behind me, Satan!"
