I recently had a conversation with someone about prophecy in the Bible. He asked a question that many people have wondered about, even if they’ve never said it out loud. He said, “Is prophecy really God telling the future, or is it just people later on reading it and then trying to make it happen?” In other words, is prophecy truly supernatural, or is it something humans could manipulate after the fact?
That same morning, I had been reading Isaiah 44:28, and the timing of it felt almost too perfect. In that verse, Isaiah records God speaking about the rebuilding of Jerusalem. It wasn’t written as a hopeful idea or a vague prediction. It was written as a certainty. What makes this remarkable is that Isaiah wrote it around 200 years before it happened. At the time Isaiah wrote those words, Jerusalem had not yet been destroyed, and no one living in that moment would have been able to imagine the exact chain of events that would have to take place for that prophecy to be fulfilled.
Jerusalem would eventually be completely destroyed by the Babylonian Empire. The city would be devastated, the temple ruined, and the people taken into captivity. That alone would have seemed like the end of everything. But Isaiah’s prophecy didn’t stop at destruction. For Jerusalem to be rebuilt, Babylon would have to fall, and another empire would have to rise in its place. Persia would have to take control of the world stage. Then a king would have to be born, come to power, and issue a decree allowing Jerusalem to be rebuilt.
And Isaiah doesn’t just predict that a king will do it—he names him. Cyrus. The prophecy identifies Cyrus before Cyrus even existed. We can read it today and treat it as history because we already know how it turned out, but Isaiah wrote it before any of it happened. The destruction, the rise of Persia, and the reign of Cyrus were all future events at the time the prophecy was written. That is not something people could “act out” to make it come true, because it involved nations, empires, warfare, rulers, and the shifting of global power.
As our conversation continued, we moved from Jerusalem to Jesus. That is when the weight of prophecy becomes even clearer. Isaiah 53 describes the suffering of the Messiah in a way that aligns with the crucifixion of Christ. It speaks of rejection, suffering, being wounded for the sins of others, and dying as an innocent sacrifice. Isaiah wrote those words centuries before Jesus was born and long before Rome perfected crucifixion as an instrument of torture and execution.
That is what makes the argument that people “lived it out” so difficult to accept. The Roman soldiers who crucified Jesus were not trying to fulfill Hebrew prophecy. They were not studying Isaiah. Many of them likely could not even read. They were simply carrying out an execution. Yet their actions aligned with what Isaiah wrote long before they ever existed.
That is when I realized prophecy is not just information about the future. It is evidence of who God is. God gives prophecy to show that He is not limited by time. He sees what humans cannot see. He declares what will happen before it happens. And He sets a clear standard: if what He says does not come to pass, then His Word cannot be trusted. But if what He says happens exactly as written, then it becomes proof that His Word is true.
This reminds me of a well-known quote by C.S. Lewis: “You must make your choice. Either this man was, and is, the Son of God: or else a madman or something worse.” That quote fits because fulfilled prophecy forces a decision. If God truly spoke through Scripture, then the Bible cannot be treated as merely a collection of moral teachings. It is either divine truth, or it is not.
That is where Romans 8:29 connects directly into this discussion. The verse says, “For whom He foreknew, He also predestined…” It begins with foreknowledge. God does not say He forced people into salvation. He says He foreknew them. The same God who knew the future of nations also knows the hearts of individuals. He already knows who will accept His offer of salvation. He already knows who will respond to His grace.
This also ties into the fact that salvation is a gift. A gift is not earned. It is not worked for. It is received. Accepting a gift is not an act of achievement, but an act of trust. Scripture is clear that salvation is not of works. We do nothing to deserve it. We simply accept what Christ has done for us.
And that is where prophecy becomes deeply personal. If God was right about Jerusalem, and right about Cyrus, and right about the suffering of Christ, then He must also be right about salvation. If He has proven His truth through fulfilled prophecy, then what He says about forgiveness, eternal life, judgment, and the future must also be true.
The Bible also speaks clearly about future events that will unfold on the earth itself. Scripture warns that in the last days the world will not gradually improve, but will grow darker in many ways. Jesus spoke of wars and rumors of wars, of nations rising against nations, and of distress among the people. The Bible describes a world filled with fear, confusion, deception, and unrest. It speaks of moral decay, where what is evil will be called good and what is good will be called evil. It warns that many will fall away from truth, not because truth is unavailable, but because hearts will grow cold and people will prefer lies that satisfy them over truth that convicts them.
The Bible also speaks of Israel and Jerusalem continuing to be at the center of world attention. It describes a time when nations will gather against Israel, and the city of Jerusalem will become a burdensome stone to the world. For centuries people questioned how such a small nation could hold such prophetic significance, yet today the world’s eyes remain fixed on that region, just as Scripture foretold. The same city Isaiah spoke about rebuilding is still central in the story of prophecy, proving that God’s timeline has not ended.
Scripture also warns of a coming world system that will seek to unify politics, economics, and religion under one controlling power. It describes a time when buying and selling will be restricted, when global control will increase, and when deception will become so strong that many will be led astray. It speaks of false peace, false unity, and false promises that appear to solve the world’s problems but ultimately lead to oppression and judgment. The Bible does not describe the future as random chaos, but as a carefully unfolding plan, moving toward a climax that God has already declared.
The Bible also speaks of a great period of tribulation on the earth, a time of suffering unlike any the world has seen. It describes judgments that will affect nations, economies, and nature itself. It speaks of earthquakes, famine, and calamities that will shake humanity and reveal how fragile human power truly is. The world will attempt to solve these crises through human strength, but prophecy makes it clear that mankind will not be able to fix what is coming without God.
Yet even in these warnings, prophecy is not written to produce fear but to produce preparation. God does not reveal the future to terrify His people but to remind them that nothing is out of control. Even the darkest events are not outside His authority. The Bible shows that God’s purpose is not destruction, but redemption. He is calling people to Himself before the final events unfold.
And at the center of it all stands the return of Jesus Christ. The same Christ who came first as a suffering servant will return as King. Scripture describes Him coming not quietly, but visibly and powerfully. It describes the nations being humbled and the reign of Christ being established on earth. The Bible speaks of a coming kingdom where Christ will rule with justice, where righteousness will be restored, and where God’s authority will finally be acknowledged by all creation.
So prophecy is not simply about proving God’s Word is accurate. It is about showing us that God is moving history toward an appointed end. The same God who accurately spoke of Cyrus, Jerusalem, and the cross has also spoken of what is still coming. And if He has been right about everything behind us, then we should take seriously everything still ahead of us.
In the end, prophecy leaves us with one clear truth: God has not only written history—He has written the future. And if He is right about the future, then He is right about salvation. The greatest question is not whether prophecy is true, but whether we will accept His gift of grace while there is still time.
