Ephesians 6:17

And take the helmet - The helmet was a cap made of thick leather, or brass, fitted to the head, and was usually crowned with a plume, or crest, as an ornament. Its use was to guard the head from a blow by a sword, or war-club, or battle-axe. The cuts will show its usual form.

Of salvation - That is, “of the hope of salvation;” for so it is expressed in the parallel place in 1 Thessalonians 5:8. The idea is, that a well-founded hope of salvation will preserve us in the day of spiritual conflict, and will guard us from the blows which an enemy would strike. The helmet defended the head, a vital part; and so the hope of salvation will defend the soul, and keep it from the blows of the enemy. A soldier would not fight well without a hope of victory. A Christian could not contend with his foes, without the hope of final salvation; but, sustained by this, what has he to dread?

And the sword - The sword was an essential part of the armor of an ancient soldier. His other weapons were the bow, the spear, or the battle-axe. But, without a sword, no soldier would have regarded himself as well armed. The ancient sword was short, and usually two-edged, and resembled very much a dagger.

Of the Spirit - Which the Holy Spirit furnishes; the truth which he has revealed.

Which is the word of God - What God has spoken - his truth and promises; see the notes on Hebrews 4:12. It was with this weapon that the Saviour met the tempter in the wilderness; Matthew 4. It is only by this that Satan can now be met. Error and falsehood will not put back temptation; nor can we hope for victory, unless we are armed with truth. Learn, hence:

1. That we should study the Bible, that we may understand what the truth is.

(2)We should have texts of Scripture at command, as the Saviour did, to meet the various forms of temptation.

(3)We should not depend on our own reason, or rely on our own wisdom.

A single text of Scripture is better to meet a temptation, than all the philosophy which the world contains. The tempter can reason, and reason plausibly too. But he cannot resist a direct and positive command of the Almighty. Had Eve adhered simply to the Word of God, and urged his command, without attempting to “reason” about it, sire would have been safe. The Saviour Matthew 4:4, Matthew 4:7,Matthew 4:10, met the tempter with the Word of God, and he was foiled. So we shah be safe if we adhere to the simple declarations of the Bible, and oppose a temptation by a positive command of God. But, the moment we leave that, and begin to parley with sin, that moment we are gone. It is as if a man should throw away his sword, and use his naked hands only in meeting an adversary. Hence,

(4) We may seethe importance of training up the young in the accurate study of the Bible. There is nothing which will furnish a better security to them in future life, when temptation comes upon them, than to have a pertinent text of Scripture at command. Temptation often assails us so suddenly that it checks all “reasoning;” but a text of Scripture will suffice to drive the tempter from us.
