There are seasons when life feels less solid than it used to.
Sometimes the change arrives all at once. A diagnosis alters the future we had imagined. A job that seemed secure suddenly is not. A relationship changes, a church disappoints us, or a plan we quietly expected to work begins to unravel. At other times, the instability is harder to locate. Nothing has completely collapsed, but the world feels less predictable. Institutions we trusted appear fragile, technology moves faster than we can process, and every week seems to bring another reason to wonder what might happen next.
When life feels like that, most of us reach instinctively for some form of control. We want more information, a clearer timeline, or a plan that accounts for every possible outcome. We tell ourselves that once we understand what is happening, once the decision is made, or once the situation settles, then we will be able to breathe again.
Without realizing it, we can begin making predictability a prerequisite for faithfulness. We assume we could trust God more easily if he would first explain what he is doing.
Hebrews 12 gives us something better than an explanation of every uncertain circumstance. It directs our attention to a kingdom that cannot be shaken.
What Hebrews Means by Shaking
Hebrews 12:18–29 moves from Sinai to Zion. The writer first recalls the terrifying scene at Mount Sinai, where the mountain burned with fire and the people trembled before the holiness of God. He then reminds these believers that they have come to Mount Zion, to the heavenly Jerusalem, to the gathered people of God, and to Jesus, the mediator of the new covenant.
That contrast matters because the warning in verse 25 does not appear in isolation: “See that you do not refuse him who is speaking.” The God who spoke at Sinai is still speaking, but believers now draw near through Jesus, whose sacrifice has secured access to God and whose blood speaks a better word than the blood of Abel.
The writer then reaches back to the prophet Haggai and speaks of a coming shaking of heaven and earth. He explains that this shaking will remove what can be shaken so that what cannot be shaken may remain.
We need to be careful here. Hebrews is not teaching us to identify every political crisis, economic downturn, technological disruption, church conflict, or personal hardship as the fulfillment of this promised shaking. The passage is looking toward God’s final judgment and the completion of his redemptive purposes. It is an eschatological promise, not a code for interpreting every alarming headline.
Present instability is not the final shaking described in Hebrews, but it can still reveal what we have been trusting. When something we assumed was secure begins to move, we discover how much weight we had placed upon it.
What Are We Asking to Remain Unshakable?
There are many good things in this life that we naturally want to remain stable. We want our families to be healthy. We want our work to provide for us. We want churches to be faithful, institutions to function, and leaders to act wisely. We want enough order in the world to make plans with some confidence that tomorrow will resemble today.
Those desires are not inherently wrong. Scripture does not call us to become indifferent to our families, our work, our churches, or the condition of the world around us. The problem begins when a good gift starts carrying the weight of an ultimate refuge.
We may never say that our security rests in our job, our health, our nation, our savings, or our ability to understand what is happening. Yet our response when those things are threatened can expose how deeply we depend upon them. Anxiety often reveals more than our circumstances. It can reveal the outcome we believe we must control, the thing we are terrified of losing, or the condition we have quietly placed upon our obedience.
We begin to think, “I can be faithful once I know my family will be all right. I can serve once the pressure at work settles. I can trust God once I understand where this is going. I can have peace once the world becomes less threatening.”
Hebrews does not promise that those conditions will be met. Instead, it asks us to relocate our confidence.
The temporary things of this life were never meant to bear the full weight of our hope. That does not make them unimportant, but it does mean they cannot provide the kind of security only God can give.
You Have Come to Zion
Before Hebrews tells believers that a final shaking is coming, it reminds them where Christ has already brought them.
“You have come to Mount Zion,” the writer says. Through Jesus, believers already belong to the city of the living God and to the kingdom that will remain when everything temporary is finally removed. This does not mean Christians escape the suffering and uncertainty of the present age. The original readers of Hebrews knew public shame, opposition, loss, spiritual weariness, and the temptation to turn back. Their circumstances did not look secure.
Their confidence rested in something deeper than their circumstances. Jesus had brought them near.
Christ is not a religious addition to an otherwise ordinary search for emotional stability. He is the mediator of the new covenant, the one whose once-for-all sacrifice gives sinners access to the holy God. His blood speaks forgiveness rather than condemnation for everyone who belongs to him. His kingdom is not fragile, his reign is not threatened, and his promises do not become uncertain because our circumstances do.
This is what makes Christian confidence different from optimism. Optimism tries to assure us that our circumstances will probably improve. Christian hope rests in realities that are already true even when circumstances remain difficult.
God reigns. Christ is risen. Jesus is interceding for his people. The Spirit is present. The church belongs to Christ. Judgment will come, evil will not have the final word, and the kingdom of God will be fully revealed.
We may not know what will happen next, but we know where history is going.
Faithfulness Does Not Have to Wait
If Christ has brought us into a kingdom that cannot be shaken, then we do not need to wait for the world to become predictable before we obey him.
We can pray while the answer remains unclear. We can tell the truth without controlling how it will be received. We can serve when our work feels unnoticed and love our families without pretending we can govern every outcome. We can make wise plans while humbly admitting that tomorrow remains in God’s hands. We can keep gathering with an imperfect church, bear one another’s burdens, and encourage weary believers who are tempted to give up.
This is not passivity. Trusting God does not mean ignoring danger, refusing to plan, or pretending painful circumstances do not matter. Faithfulness may require careful preparation, difficult conversations, courageous decisions, patient endurance, or honest lament. But there is a difference between acting responsibly and demanding sovereignty over the outcome.
That difference is often exposed in ordinary moments. We read one more article because we are convinced the next piece of information will finally make us feel safe. We rehearse a conversation repeatedly because we believe we can guarantee the other person’s response. We hold our plans so tightly that any interruption feels like a threat rather than an occasion to trust the providence of God.
Hebrews calls us away from that kind of grasping. Verse 28 says that we are “receiving a kingdom that cannot be shaken.” The kingdom is received. It is not secured by our anxiety, preserved by our strength, or maintained by our ability to manage history.
Because the kingdom is received as God’s gift, the fitting response is gratitude expressed through reverent worship. The writer does not move from the promise of an unshakable kingdom to casual comfort. He reminds us that “our God is a consuming fire.” The God who welcomes us through Christ remains perfectly holy. Grace does not make him less glorious; it gives us access to worship him with gratitude, reverence, and awe.
This is the kind of steadiness Hebrews offers. It is not the steadiness of a life in which nothing changes. It is the steadiness of belonging to Christ when everything around us does.
The world may remain uncertain. The diagnosis may not change. The decision may still be delayed. The relationship may remain difficult, and the future may refuse to explain itself. None of those things are small, and Scripture does not require us to pretend they do not hurt.
But they do not determine what is ultimately secure. Christ does. His kingdom does.
We can plan without worshiping the plan. We can grieve without surrendering hope. We can act without pretending to control the outcome. We can endure because the future does not finally depend upon our ability to hold everything together.
When everything feels as though it is moving beneath our feet, the most important question is not, “How can I make life predictable again?”
The better question is, “What does faithfulness look like here, today, as someone who belongs to Jesus Christ?”
That is a question we can answer before the circumstances change, because through Christ we are receiving a kingdom that cannot be shaken.
