Hebrews 10:23 Let us hold fast the confession of our hope without wavering, for he who promised is faithful.
In John Bunyan’s best-selling book, Pilgrim’s Progress, the central character, Christian, begins his journey leaving the city of Destruction and ventures on his way toward the Celestial City. Early on his journey, Christian decides to depart from the narrow path onto an easier one which leads him to the territory of Despair and its stronghold, Doubting Castle.
There, Christian is captured, overwhelmed, and locked in a dungeon until his faithful companion, Hope, arrives to remind him of previous victories. As the saint prays throughout the night, he remembers a key in his possession called “Promise”, which will open any lock!
At this moment, believers may be tempted to stray from the narrow path and onto an easier one shaped by worldly hopes and expectations. Doubts and uncertainties could lead to being trapped in the dungeon of Despair. However, we hold the same key of “Promise,” which opens the dungeon gate at Doubting Castle, leading us to a Kingdom that is unshaken and eternal.
Like Christian in Pilgrim’s Progress, we may find ourselves tempted to leave the narrow path, only to face the overwhelming grip of despair and doubt. Yet, just as Christian discovered the key of “Promise” that unlocked his freedom, we too possess this key—a reminder of God’s faithfulness and His unshakable Kingdom. Let us hold fast to His promises, staying on the narrow road, encouraged by hope and prayer, as we journey toward the eternal Celestial City.

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.
