Hebrews 12:26-29

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, because our God is like a fire that burns things up.
