Hebrews 12:26-28
"...'Once more I will shake not only the earth but also the heavens.' The words 'once more' indicate the removing of what can be shaken-- that is, created things--so that what cannot be shaken may remain. Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe, for our 'God is a consuming fire.'"
