Ephesians 6:10-12 Finally, my brethren, be strong in the Lord and in the power of His might. Put on the whole armor of God, so that you may be able to stand firm against the schemes of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
It ought to be obvious to all of us believers that we are in a spiritual war that is taking place all over the earth -- and that we are called to fight in this battle. In the world's armies, soldiers are not sent into battle before receiving many months of serious training. They need to get physically in shape first and then to learn how to handle different wartime situations and tactics of the enemy.
For us, the moment we are saved, the Lord begins our training for the ongoing spiritual battle in this world. It begins with learning to trust Him for protection as young believers, and progresses through many phases even to the place where we may enter strenuous wrestling with principalities and powers, as the apostle Paul describes in these verses.
Are you struggling in your walk with God? If so, realize that He is training you. Born into war, you are both protected and also necessarily engaged in the battle. Thank God for His protection and His preparation. We need both as we mature and become more involved and useful soldiers for Him against the diverse strategies and tactics of the enemy.
The Lord's weapons are spiritual; they include a knowledge of the scriptures, the anointing of the Holy Spirit which increases with a devoted prayer life, the courage which comes only with deep trust, and His divine wisdom which reveals His strategy for our present situation.
Realizing that we are in a battle, we ought to reflect on and discover where our weaknesses are. We may already be aware of some of them, but the Lord will show us if we ask Him for more insight. Our part is to cooperate with His development and sharpening of our spiritual weapons. If we cooperate with Him He will always lead us in triumph. Our present trial is the battleground for our next victory.
So, be strong in the Lord and in the power of His might. With His armor, you will stand, and with His weapons, you will win.

[worthy_plugins_devotion_single_body]Isaiah recalls the Exodus as the supreme display of God’s Z’roah, His Arm of glory. Though the people saw Moses raise his staff over the Red Sea, it was not Moses’ power that split the waters. Behind the prophet’s hand was the Arm of the LORD — majestic, glorious, and unstoppable. The sea parted not to honor Moses, but to exalt the Name of the God who sent him. The Red Sea became a stage for God to reveal His glory, so that His Name would echo through generations as the Deliverer of His people.
Jeremiah uttered these words when everything around him looked hopeless. Babylon’s armies surrounded Jerusalem, the city was on the brink of destruction, and yet God told Jeremiah to buy a field as a prophetic sign that restoration would come. The prophet responded in awe: the God who created the heavens and the earth by His outstretched arm (bizroa netuyah) is not bound by human circumstances. The same God who set galaxies in place and boundaries for the seas is the God who still moves to redeem His people. Truly, nothing is too hard for Him.
Isaiah’s words summon one of the most dramatic images of God’s saving power: the Z’roah — the Arm of the LORD — cutting Rahab in pieces and piercing the dragon.
Here, Rahab is not the woman of Jericho but a poetic name for Egypt (Psalm 87:4), often symbolizing arrogant nations and the dark spiritual powers behind them. In Hebrew poetry, Rahab also evokes the sea monster of chaos, a stand-in for the forces that oppose God’s order. To say the Arm “cut Rahab in pieces” is to recall how God shattered Egypt’s pride and broke the grip of the powers that enslaved His people.
Psalm 98 is a victory psalm — a call to lift up a “new song” because the Z’roah, the holy arm of the LORD, has brought decisive triumph. In Hebrew thought, the arm is the active extension of the will, the power that brings intention into reality. To call it “holy” is to declare that it is set apart, dedicated fully to God’s purpose, incapable of corruption. The psalmist celebrates that salvation is not a hidden act, but an open demonstration — God’s righteousness revealed before the eyes of the nations.
This is one of the most intimate revelations of the Z’roah in Scripture. God looks for a human intercessor but finds none. No man can bridge the gap. So His own Arm accomplishes the work. In Hebrew, v’tosha lo zeroa — “His arm saved for Him” — reveals that salvation originates from within God Himself, not from any outside help. Isaiah adds that His own righteousness sustained Him — it upheld His resolve to save — and His fury upheld Him, a holy passion that would not rest until justice was accomplished.
To “bare” the arm means to roll up the sleeve and reveal the full readiness for action. In Isaiah’s prophecy, this is a global unveiling — no longer hidden, the Z’roah is on display for all nations to witness. This speaks directly of Yeshua’s (Jesus’) public ministry and, ultimately, His crucifixion.
The Hebrew phrase “z’roah moshel lo” paints the picture of an arm that governs with both strength and care. The same Z’roah that brought Israel out of Egypt in power now establishes righteous order and sustains His people in love. Deliverance without rulership is incomplete; the Redeemer becomes the King — and the King rules as a Shepherd. The Arm does not act independently but moves in perfect submission to the Head, carrying out the will of the Father.
