Hebrews 12:25-28

So be careful and do not refuse to listen when God speaks. Others refused to listen to him when he warned them on earth, and they did not escape. So it will be worse for us if we refuse to listen to God who warns us from heaven. When he spoke before, his voice shook the earth, but now he has promised, “Once again I will shake not only the earth but also the heavens.” The words “once again” clearly show us that everything that was made—things that can be shaken—will be destroyed. Only the things that cannot be shaken will remain. So let us be thankful, because we have a kingdom that cannot be shaken. We should worship God in a way that pleases him with respect and fear
