Hebrews 12:28, English Standard Version
“Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe.”
Hebrews 12:18–29 gives us one of the most powerful contrasts in the book of Hebrews. The writer reminds believers that we have not come to Mount Sinai, where the people of Israel trembled before the fire, darkness, gloom, storm, trumpet blast, and terrifying voice of God. Sinai revealed the holiness of God and the seriousness of approaching Him under the law. Even Moses trembled at what he saw. The scene was not casual, light, or ordinary. It showed that sinful people cannot approach a holy God on their own terms.
But then the passage turns from Sinai to Zion. Believers have come to Mount Zion, to the city of the living God, to the heavenly Jerusalem, to innumerable angels in festal gathering, and to Jesus, the mediator of a new covenant. That is a breathtaking reality. Through Christ, we are not kept at a distance in fear, but brought near by grace. The same holy God who thundered at Sinai has opened the way for us to draw near through the blood of Jesus. We do not come because we are worthy in ourselves. We come because Christ has made the way.
This should fill our hearts with gratitude. The gospel does not lower the holiness of God. It reveals the greatness of His mercy. Sometimes people misunderstand grace and begin to treat the presence of God casually, as though access means God is less holy than He was before. But Hebrews will not allow us to think that way. The God of Sinai is still the God of Zion. The difference is not that God became less holy. The difference is that Jesus has become our mediator, our sacrifice, and our righteousness.
Because of that, Hebrews gives us a serious warning: “See that you do not refuse him who is speaking.” God has spoken through His Son, and we must not ignore His voice. If the people under the old covenant were accountable for refusing God’s warning on earth, how much more should we listen now that God has spoken from heaven through Christ? Grace is not an invitation to indifference. It is an invitation to hear, respond, obey, and worship the Lord with surrendered hearts.
The passage also reminds us that everything that can be shaken will one day be shaken. Earthly kingdoms, human accomplishments, worldly security, and temporary comforts will not last forever. God will shake what is temporary so that what cannot be shaken may remain. That truth can sound frightening if our hope is built on this world. But for those who belong to Christ, it is also deeply comforting. We are receiving a kingdom that cannot be shaken.
Therefore, our response should be gratitude and worship. We do not serve God to earn our place in His kingdom; we worship because He has graciously brought us into it. We offer acceptable worship with reverence and awe because our God is a consuming fire. Hebrews 12 reminds us that grace and reverence belong together. We come near with confidence because of Jesus, but we come with holy awe because the One we approach is still the living God. The kingdom we have received cannot be shaken, so let us listen to His voice, hold fast to His grace, and worship Him with grateful hearts.
