Isaiah 43:19 Behold, I will do a new thing; now it shall spring forth; shall ye not know it? I will even make a way in the wilderness, and rivers in the desert.
It is among popular “Christian” belief that an abundance of material and other blessings follow those whose hearts are truly after God and that those who seem to consistently struggle to that end, cannot possibly be in God’s perfect will. I want to submit to you a realization I had about this very thing. I think we might have it all backwards.
Almost all the great men of faith I’ve read about in the Bible had to spend some time in the wilderness. Abraham, Moses, John the Baptist, just to name a few.
God had to make them desperate. He had to cause them to be quiet and undistracted enough to hear His still, small voice. He had to make them hungry and thirsty enough to cry out for a miracle.
Interestingly, the word for wilderness, in Hebrew, is “meed-bahr”. And meed-bahr comes from the word “leh-da-behr”, which means to speak. Hmmm.
Some of us are walking through the desert right now. It’s hot by day — there is only rugged, thorny, sandy terrain for miles and miles and there seems no end. By night, the wind is unbearably cold and we stumble over things we can barely see. Snakes and scorpions live here. It seems like a lonely place.
But this is actually a place of blessing! It is for our growth, and ultimately for our prosperity that God has brought us here! Like it or not, the wilderness is where He can speak to us most effectively. It is the place He can most easily get our attention. It is the place we will cry out to God and truly listen for His voice.
Know that God is with you today! He is walking along with us through this wilderness and longing to comfort us! Let’s cry out to Him and heed His voice! The promised land awaits!

[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.
