2 Timothy 2:3-4 You therefore must endure hardship as a good soldier of Jesus Christ. No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier.
In Hebrew, the word for hardness is “kosher”. Interestingly enough, the word “kosher” also means “fitness”, as from a workout in the gym. Yes — it’s a workout to serve the Lord in this world — but God has called us to it!
These days, many people are working out intensely to beautify and strengthen their bodies. A lot of them are obsessed with appearance and youthfulness. It has virtually become a religion to be beautiful and/or “ripped”, and people are willing to make serious sacrifices for the sake of their bodily condition.
Believers are called to a different kind of “workout” which can be equally or even more intense. Our “obsession” isn’t with our bodies, but with our spirit. It is easy and “natural” to become caught up in the affairs of this life, even to adopt the worldly obsession with physical appearance. Yet our “workout” calls us to minimize the attention we give to worldly affairs, and to endure the hardness of spiritual warfare and service.
Are we aware of the reality of the eternal life which belongs to us, and of ALL its implications? Our life in this world is incredibly short, yet filled with tremendous opportunity for the Lord and our place in the world to come. If we want to please Him, (and we ought to think about why we would), we will make the most of our time, and work out with the greatest spiritual energy possible. That will involve saying no to worldly priorities and concentrating on spiritual ones.
If we have been chosen to be soldiers for God’s great army this is no small thing! We will increasingly disentangle ourselves from prioritizing worldly pursuits, and be seeking first the things of the Kingdom of Heaven. When we do that we have two promises: earthly provision for all of our needs [Matthew 6:23], and treasure in Heaven [Luke 18:22]. Let’s get free from the cares of this life and get focused on eternal blessings!

[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.
