Henceforth, be empowered in the Lord, and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. 12 For 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. Therefore put on the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Eph 6:10-13 WMB
Paul begins Ephesians by revealing God’s power working mightily within us then seals it with prayer for the enlightenment of the eyes of our hearts for our understanding (Eph 1:12-25). Paul reinforces this gospel of the kingdom: “of which I was made a servant according to the gift of that grace of God which was given me according to the working of his power” (Eph 3:7). Then, seals Ephesians 1 with prayer for us to be filled with the fullness of God (Eph 3:14-19).
In the last chapter of Ephesians, Paul exhorts: Henceforth, be empowered in the Lord, and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. Ephesians 6:10
We are empowered by the Lord to take the Spirit’s sword, which is the spoken word of God.
Martin Luther wrote “A Mighty Fortress Is Our God,” the battle hymn of the Reformation, in which we sing “The Prince of Darkness grim, we tremble not for him; His rage we can endure, for lo, his doom is sure, One little word shall fell him.
Yet there is more to Luther. Indeed, perhaps his greatest contribution to the faith, and one that we can still learn from today, is his understanding of God’s Word. When we hear this term, our modern evangelical minds typically go to the contemporary debates about inerrancy, infallibility, interpretation and the like. Certainly such questions are legitimate. But for Luther the central point about the Word of God was its creative power. God’s speech is the means by which he does things – makes, destroys, blesses, curses. ROBERT BRADY
The significance of rhema (as distinct from logos) is exemplified in the injunction to take “the sword of the Spirit, which is the word of God,” Eph 6:17; here the reference is not to the whole Bible as such, but to the individual scripture which the Spirit brings to our remembrance for use in time of need, a prerequisite being the regular storing of the mind with Scripture. Vines
The emphasis is on a specific word we speak. It may be a written word from the Bible or a word quickened by the Holy Spirit. Even the written word from the Bible only becomes effective when we speak it forth in the power of the Spirit.
Jesus spoke the word
When Jesus was tempted by the devil, He answered,
Man shall not live on bread alone, but on every word/rehma that proceedeth out of the mouth of God. (Mt 4:4).
There, Jesus demonstrated the spoken word by quoting the written word.
Jesus often spoke creative words of power. By Him all things were created (Col 1:15-17).
He told His disciples:
“ It is the spirit who gives life. The flesh profits nothing. The words that I speak to you are spirit, and are life” (Jn 6:63 WMB).
He called to Lazarus,
“come out.” Jn 11:43
The apostles spoke the word
Jesus told the apostles:
“But you will receive power when the Holy Spirit has come upon you. You will be witnesses to me in Jerusalem, in all Judea and Samaria, and to the uttermost parts of the earth” (Acts 1:8 WMB).
On the day of Pentecost the Holy Spirit was poured out and they received power. Peter spoke to the crowd and they gladly received his word
Peter said to them, “Repent, and be immersed, every one of you, in the name of Yeshua the Messiah for the forgiveness of sins, and you will receive the gift of the Holy Spirit. For the promise is to you, and to your children, and to all who are far off, even as many as the Lord our God will call to himself.” With many other words he testified, and exhorted them, saying, “Save yourselves from this crooked generation!”
“Then those who gladly received his word were immersed. There were added that day about three thousand souls. They continued steadfastly in the emissaries’ teaching and fellowship, in the breaking of bread, and prayer. Fear came on every soul, and many wonders and signs were done through the emissaries.” Acts 2:38-42 WMB
The work of the faith in power
…we do pray always for you, that our God may count you worthy of the calling, and may fulfill all the good pleasure of goodness, and the work of the faith in power, that the name of our Lord Jesus Christ may be glorified in you, and ye in him, according to the grace of our God and Lord Jesus Christ. 2 Thessalonians 1:11-12 YLT
Just before He ascended Jesus spoke the word to the 11 apostles saying these signs will follow them that believe the gospel of the kingdom.
15 Then He said to them,
“Go the whole world over, and proclaim the Good News to all mankind. 16 He who believes and is baptized shall be saved, but he who disbelieves will be condemned. 17 And signs shall attend those who believe, even such as these. By making use of my name they shall expel demons. They shall speak new languages. 18 They shall take up venomous snakes, and if they drink any deadly poison it shall do them no harm whatever. They shall lay their hands on the sick, and the sick shall recover.”
19 So the Lord Jesus after having thus spoken to them was taken up into Heaven, and sat down at the right hand of God. 20 But they went out and made proclamation everywhere, the Lord working with them and confirming their Message by the signs which accompanied it. Mark 16:15-20 WNT
