Matthew 12:46-50 While he yet talked to the people, behold, his mother and his brothers stood outside, desiring to speak with him. Then one said unto him, Behold, your mother and your brothers stand outside, desiring to speak with you. But he answered and said unto him that told him, Who is my mother? and who are my brothers? And he stretched forth his hand toward his disciples, and said, Behold my mother and my brothers! For whosoever shall do the will of my Father who is in heaven, the same is my brother, and sister, and mother.
Luke 8:19-21 Then came to him his mother and his brothers, and could not reach him for the crowd. And it was told him by some who said, Your mother and your brothers stand outside, desiring to see you. And he answered and said unto them, My mother and my brothers are these who hear the word of God, and do it.
When I teach about “understanding the will of God,” I’d like to talk about a story that is told in all the synoptic gospels, except that Luke’s account gives a significant nuance. (Many skeptical Bible “critics” point out differences in the gospels to argue that they can’t be reliable — yet it’s actually the differences that support the validity of these accounts because they reveal that the events recorded were simply experienced and told from slightly different viewpoints, a very common circumstance when people are telling a story.)
The gospels of Matthew and Mark give an account of the Lord’s mother and brothers arriving to see Him and wanting to speak with Him, though they were hindered because there were so many people around Him. Yeshua (Jesus) takes this opportunity to define a broad new “family” principle when He says, “… whoever does the will of my Father in heaven is my brother and sister and mother.” But Luke’s account adds something, “those who hear the word of God and do it!”
The word of God is going out across the whole world, and many are hearing it. Those who are acting on what it says are defined as the true family of Yeshua!
Here, then, is another simple approach to living in the will of God. Read His Word — and don’t be a hearer only — but be a doer who acts according to what he hears or reads. If you do, you reveal that you are a close relative of the Son of God, and that’s a relationship better than any other in the world!

[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.
