Psalms 103:5 Who satisfieth thy mouth with good things; so that thy youth is renewed like the eagle’s.
From the moment we were conceived we began aging, growing older by the day. We may slow down the physical aging process by exercising, eating right and other natural techniques – but we cannot ultimately stop it. This mortal flesh, our outer man, is “wasting away” and moving toward decay as we await the immortal bodies promised us in the Resurrection.
Yet this scripture offers us a renewal of our youth. And we see some remarkable examples of this, especially in the Old Testament. It is said of Moses at the age of a hundred and twenty that “his eyes were not weak nor his strength gone.” [Deuteronomy 34:7] Caleb had this testimony: “So here I am today, eighty-five years old! I am still as strong today as the day Moses sent me out; I’m just as vigorous to go out to battle now as I was then.” [Joshua 14:10-11]. Even after the flood of Noah’s day, it seems we have some access to longevity and vigor.
We have all heard of the “Fountain of Youth”. You can still drink from a spring in St. Augustine Florida, commemorating the Spanish explorer, Ponce De Leon’s legendary search for it. Ponce’s body is long gone. And however long he survived, I suggest he was looking for the wrong “Fountain”.
Our Spring of Living Water, our source of youth and vigor is our God, our Father in Heaven, His Son Yeshua (Jesus), and His Presence and His indwelling Holy Spirit. The Way, the Truth, and THE LIFE, lives within every born again believer. Dwelling in His Presence is the fountain of renewed youth for us.
Moses spent great amounts of time in and near the Presence of God. Check it out for yourself. Moses even glowed from it, once, and it clearly affected his physical constitution. Spending time with God, in His Presence, in His Word, will renew your youth; physically, emotionally, and spiritually.
Are you feeling old today? Get into His Presence; get into His Word, and be renewed once again!

[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.
