Have an Undivided Heart!

1 Chronicles 12:33 Of Zebulun, there were 50,000 who went out in the army, who could draw up in battle formation with all kinds of weapons of war and helped David with an undivided heart.

Colossians 3:23-25 Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.

50,000 soldiers from the tribe of Zebulun served in David’s army with UNDIVIDED (some translations: “not double-hearted”) hearts. Can you imagine a skilled army with this level of loyalty and devotion?

An undivided heart is one of the most powerful things on earth. Singleness of purpose will flow from the life of a person whose heart is undivided. Couples whose hearts are devoted to the Lord this way will preserve their marriages, no matter how difficult their issues and problems become. Intercessors whose hearts are filled with a single purpose will ultimately demolish terrible strongholds. Missionaries with vision and absolute loyalty, will be able to take entire nations for Christ. One woman will pour out ointment worth a year’s salary on her savior’s head. An undivided heart is one of the most powerful things on earth.

Yeshua (Jesus) inspires and empowers undivided hearts. If you really know him well, you will be very much like the men of Zebulun were in their loyalty toward David.

Check your heart. Is it inspired by the beauty, heroism, and love of the Messiah? If not, you just don’t know him well enough.

King David wrote these words generations before the empty tomb shook the foundations of death. At first glance, Psalm 16 reads like a personal prayer of trust — a yearning for security and closeness with God. But beneath the surface, the Spirit was revealing something deeper, something eternal: a promise not just for David, but for all of us.

The majestic Messianic prophecy of Isaiah 9 culminates in a powerful declaration: “The zeal of the Lord of hosts will perform this.” Not might. Not maybe. Not if we work hard enough. It will be done — because God Himself is passionate to see it through. The Hebrew word for “zeal” here is קִנְאָה (kin’ah), which also means jealousy or burning passion. This is not passive interest — it’s the fiery determination of the LORD of Hosts to establish His Kingdom. The same fiery zeal that struck Egypt with plagues—shattering the power of false gods, that parted the Red Sea and made a way where there was none, that birthed a nation from the womb of slavery, and that drove the Son of God to the cross at Calvary — is the very zeal that will fulfill every promise declared in Isaiah 9.

In a world weary from political upheaval, moral confusion, and fleeting peace, Isaiah offers us a vision of something profoundly different—an ever-increasing kingdom ruled by a King whose justice is not compromised, whose peace is not fleeting, and whose throne is eternally secure. The phrase “of the increase of His government and peace there will be no end” speaks not just of duration, but of expansion—a kingdom that doesn’t plateau, doesn’t weaken, and doesn’t shrink back in the face of darkness. Instead, it advances, multiplies, and transforms.

In the Hebraic understanding, a name isn’t just a label—it reveals essence, identity, and destiny. Isaiah doesn’t say these are merely descriptions of the Messiah; he says His Name shall be called — meaning this is who He is. When we declare these names, we are not offering poetic praise — we are calling upon real attributes of the living King. In just one verse, the prophet unveils the depth of Messiah’s personhood, showing us that this child is no ordinary child. He is the fulfillment of heaven’s promise and the revelation of God’s nature.

In a world wearied by the failures of men, Isaiah 9:6 offers a startling promise of hope and strength: “The government shall be upon His shoulder.” This is not the language of politics as we know it — it’s the language of divine dominion. The Hebrew word for “government” here is misrah (מִשְׂרָה), a word so unique it appears only in these two verses—Isaiah 9:6 and 9:7. Unlike more common Hebrew words for government — mamlachah or memshalah, misrah speaks of a rare and elevated rule—divinely ordained, gentle in character, and eternal in scope. This is a government not imposed, but carried. Not tyrannical, but righteous and restorative.

The prophet Isaiah begins with language so familiar that it’s often read too quickly. Yet within this brief phrase lies a depth of mystery and majesty that anchors the entire gospel. “For unto us a Child is born” speaks of an earthly event–Messiah’s humanity. He was born as all men are born, taking on flesh, entering a specific culture, time, and lineage. The Hebrew word for “born” (yalad) reinforces His full identification with us. This is the miracle of the incarnation: God wrapped in the vulnerability of a newborn child.

When the Lord called us to be His ambassadors, He didn’t merely give us a message — He gave us a lifestyle to embody it. An ambassador is not just a messenger, but a living representation of the Kingdom they serve. That means our behavior, words, and example all matter deeply.
