Ephesians 6:16
"Above all, taking the shield of faith, wherewith ye shall be
able to quench all the fiery darts of the wicked."

 [4] Faith must be our shield. Above all, or chiefly,
 taking the shield of faith, v. 16. This is more
 necessary than any of them. Faith is all to all in
 us in an hour of temptation. The breast-plate
 secures the vitals; but with the shield we turn
 every way.
This is the victory over the world,
 even our faith.
We are to be fully persuaded
 of the truth of all God's promises and
 threatenings, such a faith being of great use
 against temptations. Consider faith as it
 the evidence of things not seen and the sub-
 stance of things hoped for
and it will be of
 admirable use for this purpose. Faith, as
 receiving Christ and the benefits of his
 redemption, so deriving grace from him,
 is like a shield, a sort of universal defence.
 Our enemy the devil is here called
 wicked one.
He is wicked himself, and he
 endeavors to make us wicked. His temptations
 are called
darts, because of their swift and
 undiscerned flight, and the deep wounds that
 they give to the soul;
fiery darts, by way of
 allusion to the poisonous darts which were
 wont to inflame the parts which were wounded
 with them, and therefore were so called, as the
 serpents with poisonous stings are called fiery
 serpents. Violent temptations, by which the souls
 is set on fire of hell, are the darts which Satan
 shoots at us. Faith is the shield with which we must
 quench these fiery darts, wherein we should receive
 them, and so render them ineffectual, that they
 may not hit us, or at least that they may not hurt us.
 Observe, Faith, acted upon the word of God and
 applying that, acted upon the grace of Christ and
 improving that, quenches the darts of temptation.

              Ephesians 6:17a
"And take the helmet of salvation, . . ."


Verse 17. Take the helmet of salvation] Or, as it is
   expressed, I Thess. v. 8,
And for a helmet, the hope
   of salvation.
It has already been observed, . . . that
   on the crest and other parts of the helmet were a
   great variety of emblematical figures, and that it is
   very likely that the apostle refers to helmets which
   had on them an emblematical representation of
   hope; viz, that the person should be
safe who wore
   it, that he should be prosperous in all his engage-
   ments, and ever escape
safe from battle. So the hope
   of conquering every adversary, and surmounting
   every difficulty, through the blood of the lamb, is
   as a helmet that protects the head; an impenetrable
   one, that the blow of the battle-axe cannot cleave.
hope of the continual protection, built on the
   promises of God, in which the upright follower of
   Christ feels he has a divine right, protects the
understanding from being darkened and the judg-
   ment from being confused by any temptation of
   Satan, or subtle arguments of the sophistical un-
   godly. He who carries Christ in his heart cannot be
   cheated out of the hope of his heaven.

Ephesians 6:17b
" . . . and the sword of the Spirit, which is the word of God:"



      The sword of the Spirit]
. . . The sword of which St. Paul
       speaks is, as he explains it,
the word of God; that is, the
       revelation which God has given of himself, or what we call
Holy Scriptures. This is called, the sword of the Spirit,
because it comes from the Holy Spirit, and receives its ful-
       fillment in the soul through the operation of the Holy
       Spirit. An ability to quote this on occasions, and especially
       in times of temptation and trial, has a wonderful tendency
       to cut in pieces the snares of the adversary. In God's word
       a genuine Christian may have unlimited confidence, and in
       every purpose in which it is applicable it may be brought
       with the greatest effect. The
shield, faith, and the sword-
word of God, or faith in God's unchangeable word,
       are the principal armour of the soul. . . .

When he [Paul] speaks of the Word of God in terms of `the
sword of the Spirit' in Ephesians 6:17ff.,
it is worth noting
that this is the
only attacking weapon in the Christian's
