The Sword of the Spirit
17And take the helmet of salvation, and the sword of the Spirit, which is the word of God; Ephesians 6:17
A simple study of the Greek text in Eph. 6:17, God's prophecy in Isaiah, and other imagery used throughout the Bible, will reveal that the Holy Spirit is the sword of the Spirit.
The Greek of Ephesians 6:17
According to a rule of Greek grammar, the personal pronoun agrees with its antecedent in number and gender.
In the Greek original of Eph. 6:17:
"...και την μαχαιραν του πνευματος ο εστιν ρημα θεου."
"...and the sword of the Spirit, which is the word of God."
The Greek word, ο ("which"), grammatically agrees with πνευματος ("Spirit") requiring that ρημα θεου ("the word of God") is describing "Spirit" and not "sword."
Paul is telling the Ephesians, and us as well, that the Spirit is the Word of God. Looking more closely at the text, one finds the Greek word translated "word" is ρημα, which carries a more detailed meaning of "spoken word" or "saying." ρημα is primarily used for the breath, a spoken word or saying, or voice (utterance); man lives not on earthly bread, but on spiritual bread—every spoken word which proceeds from the mouth of Father Yahweh (Matthew 4:4) (Matthew 6:11).
The Holy Spirit is "the spoken Word of God," or "God's Saying."
To further determine the identity of the sword one must turn again to the Greek language: "the sword of the Spirit" is a genitive construction. Considering the context and construction of the verse, it is most likely a "genitive of apposition."
This same grammar construct is used in John 2. Jesus spoke of "destroying the temple," and in three days he "would raise it up." The Jews were offended at this seemingly impossible feat. The Holy Spirit explains further, through John's writing.
21But he spoke of the temple of his body. John 2:21
It is clearly seen that in this verse that "the temple" and "his body" are one and the same. This is a "genitive of apposition."
In Ephesians 6:17 the same form of grammar is used.
"And (receive) the sword of the Spirit..."
In the same way, it can clearly be seen that "the sword" and "the Spirit" are one and the same. This further identifies the Spirit, now knowing that "which" agrees with "Spirit" and not "sword." God's Holy Spirit is His Spoken Word on our behalf, acting as a Sword.
The Holy Spirit is the breath of God, the voice of God, the spoken word of God, the saying of God: giving life to the lifeless, delivering a nation, rebuking the devil, and raising the dead! God's Spirit is life, and power. Jesus told us this very thing!
63It is the spirit who gives life. The flesh profits nothing. The words that I speak to you are spirit, and are life. John 6:63
The flesh profits nothing. And, as the apostle tells us elsewhere, our warfare is not according to the flesh. It is a spiritual warfare.
3For though we walk in the flesh, we don’t wage war according to the flesh; 4for the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds, 2 Corinthians 10:3,4
11Put on the whole armor of God, that you may be able to stand against the wiles of the devil. 12For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places. Ephesians 6:11,12
Receiving the Sword
The apostle tells us how to receive the sword of the Spirit in his next thought:
17And take the helmet of salvation, and the sword of the Spirit, which is the word of God; 18with all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints: Ephesians 6:17,18
We receive the sword "by means of all prayer and supplication, praying in every season, in the Spirit."
Praying in the Spirit is defined elsewhere by Paul:
14For if I pray in another language, my spirit prays, but my understanding is unfruitful. 15What is it then? I will pray with the spirit, and I will pray with the understanding also. I will sing with the spirit, and I will sing with the understanding also. 1 Corinthians 14:14,15
Remember, Paul wrote that our warfare was a matter of wrestling against the spiritual forces in high places. Thus we see this lived out, through taking up the sword of the Spirit through prayer in the Spirit.
We are to be steadfastly continuing in the prayer, without ceasing.
2Continue steadfastly in prayer, watching therein with thanksgiving; Colossians 4:2
17Pray without ceasing. 1 Thessalonians 5:17
Paul entreated the Romans to strive together with him in the prayers that he may be released from bondage in Judea to doing work of the ministry.
30Now I beg you, brothers, by our Lord Jesus Christ, and by the love of the Spirit, that you strive together with me in your prayers to God for me, Romans 15:30
We also see this teaching of Paul lived out during his days, through a fellow-Christian of the Colossian church, and student of Paul, Epaphras; he struggled in the prayers for the saints so they were able to become united, matured and completed in the will of God.
12Epaphras, who is one of you, a servant of Christ, salutes you, always striving for you in his prayers, that you may stand perfect and complete in all the will of God. Colossians 4:12
Indeed, prayer in the spirit is a matter of wrestling, struggling, striving and fighting against of the enemy of God and our souls, for the kingdom of God!
Killing fleshly deeds with the Sword
In the same way, we can use this sword to put to death the deeds of the flesh: namely, the sinful desires and thoughts, through prayer in the Spirit. This will cause us to be built up, once sin is put away from us, and we shall unite with other members of the Body of Christ in one!
13For if you live after the flesh, you must die; but if by the Spirit you put to death the deeds of the body, you will live. Romans 8:13
16But I say, walk by the Spirit, and you won’t fulfill the lust of the flesh. Galatians 5:16
According to Paul here, we can live above sin through the Spirit! What can do we, through the Spirit, that will "kill" things? Use our Sword, which is the Spirit! How? Pray in the Spirit!
This practice will ultimately bring us closer to the perfect image of Christ, who had no sin, neither in thought nor deed. Through weilding our sword in prayer, we become more and more like Him!
18But we all, with unveiled face seeing the glory of the Lord as in a mirror, are transformed into the same image from glory to glory, even as from the Lord, the Spirit. 2 Corinthians 3:18
21if indeed you heard him, and were taught in him, even as truth is in Jesus: 22that you put away, as concerning your former way of life, the old man, that grows corrupt after the lusts of deceit; 23and that you be renewed in the spirit of your mind, 24and put on the new man, who in the likeness of God has been created in righteousness and holiness of truth. Ephesians 4:21-24
20But you, beloved, keep building up yourselves on your most holy faith, praying in the Holy Spirit. Jude 1:20
Praise the Living God, Yahweh of Hosts!
This idea is confirmed at the end of Isaiah's prophecy about Yahweh Himself coming down to fight the battle for us, with the armor previously mentioned — a prophecy made hundreds of years before Paul wrote to the Ephesians.
19So shall they fear Yahweh’s name from the west, and his glory from the rising of the sun; for he will come as a rushing stream, which Yahweh’s breath drives. 21“As for me, this is my covenant with them,” says Yahweh. “My Spirit who is on you, and my words which I have put in your mouth, shall not depart out of your mouth, nor out of the mouth of your offspring, nor out of the mouth of your offspring’s offspring,” says Yahweh, “from henceforth and forever.” Isaiah 59:19,21
"His words": applied to the fulfillment of this prophecy, seen in Paul's teachings, they are the words spoken in other languages by the inspiration of the Spirit. Yahweh's Words "will not be removed from our mouths" — we may speak His words whenever we wish (praying in other languages), because "His Spirit is on us" at all times, never to be removed, to do the inspiring of the very words! Praise Him forever!
