Ephesians 6:17

take—a different Greek word from that in Ephesians 6:13, Ephesians 6:16; translate, therefore, "receive," "accept," namely, the helmet offered by the Lord, namely, "salvation" appropriated, as I Thessalonians 5:8, "Helmet, the hope of salvation"; not an uncertain hope, but one that brings with it no shame of disappointment (Romans 5:5). It is subjoined to the shield of faith, as being its inseparable accompaniment (compare Romans 5:1, Romans 5:5). The head of the soldier was among the principal parts to be defended, as on it the deadliest strokes might fall, and it is the head that commands the whole body. The head is the seat of the mind, which, when it has laid hold of the sure Gospel "hope" of eternal life, will not receive false doctrine, or give way to Satan's temptations to despair. God, by this hope, "lifts up the head" (Psalms 3:3; Luke 21:28).

sword of the Spirit—that is, furnished by the Spirit, who inspired the writers of the word of God (II Peter 1:21). Again the Trinity is implied: the Spirit here; and Christ in "salvation" and God the Father, Ephesians 6:13 (compare Hebrews 4:12; Revelation 1:16; Revelation 2:12). The two-edged sword, cutting both ways (Psalms 45:3, Psalms 45:5), striking some with conviction and conversion, and others with condemnation (Isaiah 11:4; Revelation 19:15), is in the mouth of Christ (Isaiah 49:2), in the hand of His saints (Psalms 149:6). Christ's use of this sword in the temptation is our pattern as to how we are to wield it against Satan (Matthew 4:4, Matthew 4:7, Matthew 4:10). There is no armor specified for the back, but only for the front of the body; implying that we must never turn our back to the foe (Luke 9:62); our only safety is in resisting ceaselessly (Matthew 4:11; James 4:7).
