Hebrews 12:26-29 NKJV
whose voice then shook the earth; but now He has promised, saying, “Yet once more I shake not only the earth, but also heaven.” Now this, “Yet once more,” indicates the removal of those things that are being shaken, as of things that are made, that the things which cannot be shaken may remain.
Therefore, since we are receiving a kingdom which cannot be shaken, let us have grace, by which we may serve God acceptably with reverence and godly fear. For our God is a consuming fire.
