James 4:7 Therefore submit to God. Resist the devil and he will flee from you.
Carl Armerding wrote a funny story in Moody Monthly, about his experience at the zoo. “As I stood there,” he said, “an attendant entered the cage through a door on the opposite side. He had nothing in his hands but a broom. Carefully closing the door, he proceeded to sweep the floor of the cage.”
He observed that the worker had no weapon to ward off an attack by the beast. In fact, when he got to the corner of the cage where the wildcat was lying, he poked the animal with the broom. The wildcat hissed at him and then lay down in another corner of the enclosure.
Armerding remarked to the attendant, “You certainly are a brave man.” “No, I ain’t brave,” he replied as he continued to sweep. “Well, then, that cat must be tame.” “No,” came the reply, “he ain’t tame.” “If you aren’t brave and the wildcat isn’t tame, then I can’t understand why he doesn’t attack you.” Armerding said the man chuckled, then replied with an air of confidence, “Mister, he’s old — and he ain’t got no teeth.”
Such is the devil in our lives when we realize that God is for us! We should be like the attendant. He knew that cat couldn’t hurt a fly. Satan will make a big ruckus, fussing and growling all he wants but we need to keep our eyes focused on our Lord.
Are you being growled at today? The enemy would love nothing more than to make us feel powerless against him — but “he ain’t got no teeth” next to our Lord! Let’s turn to God and put our trust in Him. If God is for us, who can be against us?!

[worthy_plugins_devotion_single_body]Isaiah’s vision looks ahead — not only to the Arm of the LORD revealed in the Exodus or even in the cross, but to the day when that same Arm will come again in glory. This is not a picture of brute force but of purposeful arrival. The Z’roah — the Arm of the LORD — comes clothed with strength to establish His rule, and He does not come empty-handed. His reward is with Him, and His work is before Him. The promise is sure: He is coming, and He is rewarding.
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.
