If you ever find yourself wondering whether God really exists, Isaiah 45 offers one of the most remarkable proofs in all of Scripture. And I don’t use that word lightly—proofs.
Long before Cyrus ever ruled the Persian Empire, Isaiah wrote that God would raise up a world leader and even called him by name: Cyrus.
Cyrus didn’t come to power until 559 B.C., about 150 years after Isaiah’s prophecy. Yet Isaiah records these incredible words:
"Thus says the LORD to his anointed, to Cyrus, whose right hand I have grasped, to subdue nations before him and to loose the belts of kings, to open doors before him that gates may not be closed: ... I will give you the treasures of darkness and the hoards in secret places, that you may know that it is I, the LORD, the God of Israel, who call you by your name. For the sake of my servant Jacob, and Israel my chosen, I call you by your name, I name you, though you do not know me." (Isaiah 45:1, 3–4 ESV).
Can you imagine Cyrus’s reaction when someone—perhaps Daniel—read him these words written a century and a half before he was born? How humbling it must have been to hear his name spoken by the God of heaven long before his empire existed. Maybe that moment is what turned his heart toward God, moving him to accomplish exactly what the Lord had planned.
Cyrus became the instrument through which God allowed His people to return home and rebuild the temple. As Isaiah wrote:
"Who says of Cyrus, 'He is my shepherd, and he shall fulfill all my purpose'; saying of Jerusalem, 'She shall be built,' and of the temple, 'Your foundation shall be laid.'" (Isaiah 44:28 ESV).
Of course, not everyone accepts this as evidence of God’s sovereignty. Many modern scholars claim that this portion of Isaiah must have been written during Cyrus’s reign and later added to the scroll. They have to say that, because if Isaiah truly wrote this prophecy 150 years before, it stands as a devastating challenge to a worldview that refuses to acknowledge God.
But for those of us who kneel before King Jesus, Isaiah 45 strengthens our faith. It reminds us that belief in God is not built on fables or wishful thinking. It’s rooted in truth—in the God who reveals Himself through both prophecy and history.
Faith will always be part of the equation. But God has not left us without evidence. Jesus told Thomas that those who believe without seeing are blessed. And the writer of Hebrews says:
"And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him." (Hebrews 11:6 ESV).
Isaiah’s prophecy about Cyrus isn’t the foundation of our faith, but it is a powerful reminder that our confidence in God rests on solid ground. When we see how precisely God fulfills His word, we’re reminded that He is still in control—over nations, over history, and over our own lives.
So, what about you? How does this glimpse into God’s faithfulness stir your faith today? Take a moment to reflect on where you’ve seen His hand at work, and share your thoughts below. You never know how your reflection might strengthen someone else’s faith.
